How can I tell the sex of the plant? Some of my plants have little spines on them. Are these male plants or female?
First, from reading that, I dont think its very good for your plant to go 12/12 then back to 18/6 or whatever you had it at for normal, im pritty sure that will promote it to be a hermie. Since the guide didn't answer your question, males have little balls on them, growing out of the nodes, and the females have little pistils, or hairs, growing out of their nodes. The two pistils are the forming of those little red hairs in weed plants.
