Gnat Wars
I harvested the winter round and started more for the spring. Just before I flipped I noticed what I thought was a nutrient burn, turns out it was the first shot in a major PIA. Although I have used Lucas before and not seen any problems, I switched to General Hydro drain to waste and noticed an oily slick in the runoff and missed the significance.

After a collapse of a white widow in week 4 of flower (showing every deficiency you could imagine) I undertook a closer examination and found plenty of gnats. As a general rule I dont use chemical insecticides on my plants (the Borg being a notable exception) so I am employing an additional fan, sticky traps and 4 to 1 water/H2O2 every 4th day. I an currently in day 41 of flower. The count on the sticky traps is dropping closer to zero..
Day 44 zero gnats today. I can hear you thinking and your right. Aside from the obvious damage there is evidence of leaf necrosis spread through out the plants. The only exception is a white widow spear I stuck in a 4 X 5 opening in the lattice. It looks like nitrogen toxicity, but no damage. The clone mate was the plant I lost. I will run the H202 every third day for the next two cycles, but considerable damage has been done.
