so my seeds just sprouted (first grow), and 3 outta the 4 have nice green stems with there first leaves showing, the 4th stem is purple and thin, and just fell over tonight, no support. I just transplanted them 4days ago from root plugs to light warrior medium. They have been under 24watt t5 since in the soil for 18/6..I did notice last night they were pretty dry, so i watered them accordingly. Could there have been too much moisture when I transplanted them causing root rot? any ideas?
