1. Seeds fail to germinate.
Possible Causes:
*Temperature is too hot or too cold.
*Seeds are planted too deeply or not deeply enough (they may need more contact with soil).
*Your growing medium was allowed to dry out.
*The seeds are old or improperly stored.
*Damping off disease (seeds rotted in soil).
*Improper light (some seeds require light or darkness to germinate).
2. Seedlings fall over or start to decay at soil level.
This may be a sign of damping off disease (organisms attacking seeds and young plants). Once plants have been afflicted, reviving them is not possible.
Possible Causes:
*Soil not sterilized.
*Dirty growing containers.
*Improperly spaced seedlings.
*Poor air circulation.
*Excessive moisture.
*Stress from low light or cool temperatures.
3. Leaves start to curl under.
Possible Causes:
*Too much light.
*Over fertilization.
4. Growth appears stunted or dwarfed.
Possible Causes:
*Poor soil fertility.
*Low temperatures.
5. Seedlings have pale, or discolored leaves.
Possible Causes:
*Insufficient lighting.
*Fertilizer burn.
*Excessive watering.
*Nutrient deficiency (nitrogen and phosphorus)
6. Seedlings have leggy, spindly growth.
Possible Causes:
*Insufficient light.
*Overcrowding of seedlings.
*Too much fertilizer.
*Temperatures too high.
*Excessive watering.
7. Seedlings have poorly developed roots (as seen when transplanting).
Possible Causes:
*Poor drainage.
*Low soil fertility.
*Damage from fertilizer salts.
*Low temperatures.
*Compacted soil (lack of air space in growing medium).
8. Moss or mold is taking over your growing medium.
Possible Causes:
*Lack of air circulation.
*Excessive moisture.
Possible Causes:
