Athosanswered grow question 7 years ago You say you give them an equivalent of half a liter per day of water and that you are also feeding them too? That's too early to be feeding, since they are too small and it's too much water, let the pots really dry up before watering again with plain pH'ed water, no nutes and no more than half a liter of water. Also put more distance between the plants and the lights, there's signs of a bit of heat stress (some leaves edges curling up)
