I'm a first time grower and having a problem with my clones. It been a week and I think I over watered them in rock wool. Thy started out looking good but the last couple of days the leaves started to curle up and the tops are turning yellow. Looking for some help. Thanks
Are the leaves yellow, but the veins remain green. If yes, this sounds like textbook case of MG deficiency. http://www.greenmanspage.com/guides/plant_abuse.html Check out magnesium. Even if your veins aren't green still consider magnesium. Remember, foliar feed them. (spray solution on the leaves to be absorbed). o/ Tieme
Yeah...that could be too. Clones can't take up as much water as a normal plant until they establish their roots so even a little too much heat could dry them out pretty bad. Good point, doworkson. o/ Tieme
