My seedlings made the last problem and i recently transplanted them and came across another problem , one of my babies has brown/yellow lines on the leaves Temp is 76 and Im using T5 bulbs so dont think its light burn http://tinypic.com/r/28iuueh/8
I see no lines that you speak of. I think the transplant caused the slight burn on the leaf tips. Did you go from a seed starter mix to a fully hot soil, something like ff ocean forest? In a newly developing root system, this can happen if the plant gets an overload of nitrogen or otherwise.
