In early stages of growth, sometimes the plants will do this. Don't worry, and don't change anything unless the condition worsens. My plants always do this in the begining, b/c for some reason the first sets of leave don't stick around for too long, and if they do, they need to be pruned eventually anyway. Just keep everything steady and balanced, make sure you prune when the time is right, and stop worrying about it.
PUO Reviewed by PUO on . Yellow leaves I wish I had pictures to show this but I dont. We have a 400 MH about 22 inches away from the plants in a DWC ( Bubbler ) system which 1/2 the amount of GH certified nuets going in it with enough oxygen to provide a small town in TX. :D So anyway, one of the plants is starting to develop some yellow on the leaves. Tips and such.. What could be causing this? Too close light? Nuets? =\ Rating: 5
