Bad news - some of my plants got little black worms in their roots. After doing some research, I determined this was drain fly larvae, and that these mosquito dunks should do the trick to kill them. Neither of the Lemon Hazes' had the larvae, but they got the dunks anyway. Not supposed to harm plants but we will see if it does anything to them.
One of these girls has stretched a ton. She is going to be big, and probably take a long time to flower, typical of most sativas! They look happy and healthy though, so I defoliated and lollipopped some.
