Actually I got one more question, the clones I got were pretty bad when I got them, all the leaf endings were burnt and alot of the leaves were yellow, I flushed the plants out and have been nurturing them back to health, I have been cutting off the old leaves that look like they are dying or have almost no green at all, is that ok to do? I have afy's which don't grow big and harvest at the end of August but they haven't grown much, they are bushing out but no hight and they're only about 8" high, if that, just want to make sure that taking off the dead and yellow leaves won't stunt the plants. I only do a leaf or two at a time days apart when I seen new ones have come in on the same stem. Sorry if this is common sense stuff, this is my first grow.
