Considering this, why are my leaves curling up?
When the the serrated edges of marijuana leaves curls or tipped up like that, it's often a sign of temperature stress, overwatering/root problems or extreme humidity levels. If this is happening to the plants which are closest to your grow light, that's a hint that the problem may be temperature related.
Also Know, what's wrong with my seedlings? If the stems of your little seedlings start to get thin at the bottom, if you see spots on their leaves, and/or if they simply fall over and die, they may have damping off. The sight of mold as your seedlings emerge from the soil may also be a symptom. As with mold (more below), be sure to have good air circulation.
Subsequently, one may also ask, how do you fix sagging seedlings?
Stick an index finger 1 or 2 inches into the plant's soil. If it feels dry, the plant needs water. If the soil feels moist, another problem is causing the wilting, such as over-watering, too much wind, very bright sunlight, pests or disease. Move the wilted plant out of the sun, if possible.
Why are my seedlings falling over?
Leggy seedlings happen for the same reason crooked houseplants happen. The plant grows towards the light and, since the light is too far away, the plant tries to accelerate its height to get close enough to the light to survive. Third, seedlings that are falling over can be more prone to disease and pests.
