How to Water Seedlings in an Oversized Pot

When growing seedlings in a large container (e.g. 13 litres or bigger), it is important to water slowly, giving only a small amount at a time until the seedling has grown into the pot size.

  • Water slowly in a small circle around the stem – about 5 cm away from the base in every direction
  • If the seedling is larger, widen the circle to match the spread of the leaves
  • Always water in a circular motion until a small amount of runoff comes out of the bottom
  • Remove runoff water from the tray immediately so it is not reabsorbed
  • Do not water again until the top inch (first knuckle) feels dry to the touch
Tip: Pour the water into a separate cup first – this lets you easily water each plant in a circle without soaking the entire medium at once.
Seedling watering technique
Overwatered Plants – Symptoms and Solution

Drooping and curling leaves are the first sign of overwatering. The leaves feel firm and curl downward from the stem to the tip – they begin drooping shortly after watering. If left uncorrected, it leads to yellowing and nutrient problems.

Solution:

  • Allow more time between waterings – restart slowly
  • Increase temperature and airflow to help moisture evaporate faster
  • Carefully poke a few aeration holes into the medium with a pencil
  • Always make sure the pot has proper drainage holes!
If plants droop before watering, they have likely used up their water – water sooner. If they droop after watering and do not recover quickly, the roots may be rootbound – a larger pot may be needed!

Step 4
Some growers use the lift-the-pot method: wait until the pot feels light (plants have used up the water), then water. This is one of the most accurate ways to find the right watering rhythm.

This schedule is designed for a 20-litre pot, but your environment affects how much water your plants drink. Fabric pots dry out faster – monitor the pot weight!
Watering schedule chart
Watering Mature Plants (30+ Days Old)
  • Ensure 10–20% runoff with every watering – add enough water so approximately 10–20% more drains out of the bottom
  • Let the top layer dry out – in soil, a few centimetres deep; in coco, until the first knuckle feels dry
  • Never let plants sit in standing water – roots will suffer from lack of oxygen
  • If you want to avoid runoff (water-only substrate), give approximately 2 litres per plant every 2–3 days
If the top of the medium stays wet for too long (more than 4–5 days), you need better drainage – or a small plant has been placed in an oversized pot.
Summary – Two Watering Stages
StageWhen to applyMethod
Early stage While the top takes more than 2–3 days to dry out
Regular watering stage Once the top dries out within 2–3 days
Important: Always wait until the top inch of the medium (first knuckle depth) feels dry before watering again. This prevents overwatering and keeps fungus gnats away.

Pests & Diseases

Recognizing nutrient deficiencies, pests and fungal diseases – early detection is key to intervention.

Nutrient Deficiency Table

Plants require micro and macronutrients in small quantities, but their absence can cause significant yield loss. Recognizing visual symptoms is key to early intervention.

Macronutrients
N

Nitrogen

N

Main component of chlorophyll and proteins. Drives intensive leaf and shoot growth. Critical during the vegetative phase.

DeficiencyLower leaves yellow first, progressing upward. Slow growth, pale foliage.
P

Phosphorus

P

Root development, flower formation and energy transfer (ATP). Critical during flowering and fruit set.

DeficiencyLeaves turn purple-reddish, especially on the underside. Slow flowering, weak root system.
K

Potassium

K

Water and nutrient transport, turgor pressure, disease resistance. Especially important in the finishing phase.

DeficiencyLeaf edges brown and dry out (scorching). Weak stems, reduced resistance.
Ca

Calcium

Ca

Cell wall formation, root growth, nutrient uptake. Not mobile – continuous supply required.

DeficiencyYoung leaves deform, brown spots appear. BER (blossom-end rot) in tomatoes and peppers.
Mg

Magnesium

Mg

Center of the chlorophyll molecule. Photosynthesis, enzyme activity, aids phosphorus uptake.

DeficiencyInterveinal chlorosis: veins stay green, yellowing between them on older leaves.
S

Sulfur

S

Component of amino acids and proteins. Enzyme activator, supports terpene production.

DeficiencyUniform yellowing of young leaves (starts from top). Slow growth.
Micronutrients (Trace Elements)
Fe

Iron

Fe

Chlorophyll synthesis, nitrogen fixation, enzyme component. EDDHA chelate is pH-insensitive.

DeficiencyYoung leaves yellow, veins stay green. Most common on alkaline soils (pH>7).
Mn

Manganese

Mn

Chlorophyll synthesis, vitamin C and nitrogen metabolism. Better mobilized in acidic soil.

DeficiencyInterveinal chlorosis on young leaves, alkaline soil. Pale color, slow development.
Zn

Zinc

Zn

Component of enzyme systems, protein synthesis, growth hormone production.

DeficiencyShort internodes, small leaves, yellowing and spotting. Delayed maturity.
Cu

Copper

Cu

Reproduction, enzyme activity, chlorophyll synthesis. Aids root development and protein utilization.

DeficiencyYoung leaves yellow, then die. In extreme cases, leaves shrivel and become ragged.
B

Boron

B

Cell membrane, root and shoot growth, sugar transport. Critical for fruit set.

DeficiencyMore likely in alkaline soils. Growing points die, deformed leaves, bud drop.
Mo

Molybdenum

Mo

Nitrogen metabolism, protein synthesis, conversion of inorganic phosphates to organic forms.

DeficiencyTypical in acid soils. Pale, deformed leaves, slow growth.

Plants obtain carbon, hydrogen and oxygen from air and water – these make up the bulk of plant material. In addition to the 13 nutrients listed, these are also essential.

SHIVA Solution: SHIVA Bloom, Grow and Boost products contain EDDHA-chelated iron and a complete micronutrient package – stable at pH 3–9, immediately available. When deficiency symptoms appear, always check the pH value first!

Pests & Fungal Diseases

In indoor cannabis cultivation, the enclosed environment can favor the rapid spread of certain pests and the development of some fungal diseases. Early detection requires regular inspection of the upper and lower leaf surfaces, young shoots, and flowers.

Spider Mites
Spider Mites Very common

Tetranychus urticae

One of the most common and destructive pests in indoor cannabis cultivation. They reproduce very quickly in warm, dry environments and can infest entire crops in a short time.

SymptomsTiny white speckling on leaves; leaves turning pale or bronze; fine webbing on leaves and stems; leaves drying out; significant yield loss.
Favorable ConditionsHigh temperatures, low humidity, infested new plants, poor hygiene.
Affected PlantsCannabis, peppers, tomatoes, cucumbers, roses and many ornamental plants.
Prevention – leaf washingKeeping leaves clean regularly reduces the chance of pests settling and spreading. Using SHIVA Surface Cleaner helps remove dust, organic residues and other contaminants from leaf surfaces.
Thrips
Thrips Very common

Frankliniella occidentalis

Tiny, fast-moving insects that feed on leaf surface cells and can also transmit plant viruses.

SymptomsSilvery streaks on leaves; black fecal spots; deformed new leaves; stunted growth.
Favorable ConditionsInfested plant material, high temperatures, poor hygiene.
Affected PlantsCannabis, peppers, tomatoes, cucumbers and ornamental plants.
Prevention – leaf washingRegular leaf cleaning helps maintain a clean growing environment and reduces the risk of pests and viruses. SHIVA Surface Cleaner should be part of the routine plant care program.
Aphids
Aphids Common

Aphididae

Sap-sucking insects that feed on young shoots and leaves, weakening the plant.

SymptomsDeformed shoots; sticky leaves; stunted growth; honeydew production.
Favorable ConditionsInfested new plants, poor hygiene, dense foliage.
Affected PlantsAlmost all garden and ornamental plants.
Prevention – leaf washingRegular cleaning of leaves helps maintain a clean plant surface. SHIVA Surface Cleaner supports good hygiene and overall plant health.
Whiteflies
Whiteflies Common

Trialeurodes vaporariorum

Small white insects that live on the underside of leaves and suck plant sap.

SymptomsWhite flying insects; yellowing leaves; sticky leaves; sooty mold.
Favorable ConditionsHigh temperatures, poor ventilation, dense canopy.
Affected PlantsCannabis, tomatoes, peppers, cucumbers and ornamental plants.
Prevention – leaf washingRegular leaf cleaning supports a clean growing environment. SHIVA Surface Cleaner helps remove contaminants and maintain healthy plant conditions.
Fungus Gnats
Fungus Gnats Common

Bradysia spp.

Adult gnats cause little damage, but larvae in the soil can harm roots and reduce plant growth.

SymptomsSmall black flies around pots; slow growth; root damage; wilting.
Favorable ConditionsOverwatering, constantly wet soil, organic matter buildup.
Affected PlantsAll potted plants.
Prevention – leaf washingMaintaining a clean growing environment and regularly cleaning leaves supports good plant hygiene, but SHIVA Surface Cleaner offers no direct prevention against larvae developing in the soil – here the product should be presented purely as general plant care.
Powdery Mildew
Powdery Mildew Very common

Golovinomyces spp.

An easily recognizable fungal disease on the leaf surface. Small white spots appear at first, which can later merge into a continuous coating.

SymptomsWhite, powdery spots or coating; pale, deformed leaves; reduced photosynthetic leaf area; leaf drying in advanced stages.
Favorable ConditionsHigh or strongly fluctuating humidity, weak air circulation, dense foliage, infected plant material.
Affected PlantsCannabis, hops, cucurbits, grapevine, roses and many other plants.
Prevention – leaf washingRegular cleaning as part of plant care supports a clean leaf surface. For already visible, extensive fungal infection, cleaning alone is not a sufficient treatment.
Botrytis (Gray Mold)
Botrytis (Gray Mold) Very common

Botrytis cinerea

One of the most significant fungal diseases of flowering cannabis. Often starts inside the dense flower, making it hard to detect early.

SymptomsBrowning or dying flower parts; grayish mold growth; soft, rotting tissue; affected parts easily detach or fall apart.
Favorable ConditionsHigh humidity, persistent moisture, weak air circulation, dense flowers and damaged plant parts.
Affected PlantsCannabis, grapevine, strawberries, tomatoes, peppers and many flowering plants.
Prevention – leaf washingRecommended for the vegetative leaf area. Direct, heavy wetting of the dense flower is NOT recommended, as trapped moisture can increase the risk.
Downy Mildew
Downy Mildew Less common

Peronospora, Pseudoperonospora and Plasmopara spp.

Less common indoors, but downy-mildew-like symptoms can develop with persistently wet leaf surfaces and high humidity.

SymptomsYellowish, vein-bounded spots on the upper leaf surface; grayish-purple coating on the underside; browning, dying leaf areas; leaf drop in advanced stages.
Favorable ConditionsPersistent leaf wetness, high humidity, cooler night periods, weak air circulation.
Affected PlantsGrapevine, cucumbers, lettuce, onions, basil; less common in cannabis.
Prevention – leaf washingRegular, preventive cleaning of the leaf surface can be part of plant hygiene. After application, leaves must dry completely – persistently wet foliage should be avoided.
Summary Table

SHIVA Surface Cleaner: the "Prevention" notes above describe exclusively the role of preventive plant washing with SHIVA Surface Cleaner. Washing is a care measure that helps keep the plant surface clean – it does not replace an accurate diagnosis and is not, by itself, a sufficient solution against every pest or disease. On flowering plants, avoid prolonged wetting of the dense flower; after treatment, the surface must dry completely.
