I'm helping a friend with his first time grow. He picked these seeds out of his medical cannabis and planted them. They started to yellow towards the bottom and look unhealthy - I suspected a phosphorus deficiency. I told him it might be time to move them out of a 3 gallon into a 5 gallon. We...

So I've got these discolored leaves on the top and bottom of my plant and I just pruned it a couple days ago... My question is whether to prune it again.
