Sister Amnesia Lemon with New LED's

Hello. This is the end of week 3 and the beginning of week 4 of flowering. Everything is going great this week. I was in there earlier this week and put a string around each plant they were starting to spread and did my last trimming/pruning. Other than the odd fan leaf I'll take off I'll leave the plants alone till harvest. I'll need to get in there soon and tie up the plants better, I know I'll get some heavy buds later. I found a hermie in my other tent, so I'm hoping that no pollen found it's way in here. I've noticed some fungus gnats in here. I thought I had got rid of them when these plant were clones waiting to go into this room. This is the only room that I don't use Diatomaceous Earth in. I will use some Spinosad in the reservoir. It's a spore that attack's pests and is harmless to most other things. We are getting more unusual weather tonight. It's going down to -7 c. And Vancouver will get even colder. Thanks. Chuck.
