We have a lot going on at home so I missed a week here. But the plants seem to have responded better to upping the nutrient amount to 2/3. Color is coming back and smell is increasing. I plucked the dead leaves and now they look a little stalky - but they're alive.
BBA2 shot up to 16"! I used an LST clip just to get it down to match heights with BBA1.
I was very reluctant to feed until week 5 or at flower. Others with similar grows seem to have gotten away with this. Perhaps next time I'll feed more heavily week 4.
