Title says it all. I know its when they get a 12/12 light cycle, but what are the actual physical signs that I can see and know it has begun flowering. The reason is because I am about to come up on a plant (my buddy's giving it away), and I've seen it. Its a bit small, and frail. Still healthy lookin' though. I want to veg. it a bit more until it's more sturdy and just bigger, but i dont know if it's flowering yet, he said its about to. I can see the nodes... Also can I re-veg. the plant if its just starting to flower? Or would that be bad for it somehow? Thanks in advance.
