Got a bit of a problem with my babies pictures below, there about a month old now. They are under a 600 hps about 20" away, temp is 30 hum is 45 light on, fan blowing over them, 100 intake fan 125 outake with filter, growing in coco soil, been watering when needed, overwatered at first but sorted it know, used rhizotonic after overwatering, they are due for a feed in day or so with 1/4 nutes, ph was 7 last time i checked.
Lost a few leaves through yellowing then going brown crunchy, the yellowing was only on the bottom set of real leaves now it is gradually working it way up the plant. The new growth is a nice lush forest green, as they go lower the yellower they are becoming. PLEASE HELP
