I woke up today to see my seedling looking like this. Its in the same room as the other plant under the same lights. The plant seems to be drying, the leafs are cracking and curling upwards. But the other plant looks fine besides its a little small. Ive been watering with a mix of B-1 1tsp per gallon I watered till run off last night. Each are under a 23 watt 2700k CFL, 2 - 3" away They are both 13 days from sprout. Any idea what it could be? Damaged Plant Other Plant
I'm having a some-what similar problem with one of my plants, except mine is 46 days old and much bigger. I believe it is a potassium deficiency or magnesium deficiency, but I could be completely wrong. I just posted a thread about it, if I find out anything helpful I'll let you know.. Good Luck!!
I haven't watered with any nutes though and it happened over night Out of 3 plants this is the only one to have this problem
you should probably remove the aluminum foil from around the base of the plant. the tender leaf undersides do not like to be exposed to light like that. also foil like that will reflect light, but it is also engineered to reflect heat waves very efficiently. i would remove that and see if symptoms fade away.
