First Grow, Critical Purple

Very light defoliation, just a fan leaf here and there in total darkness. Lowered my nitrogen intake because I noticed a bit of leaf tip curling after feeding. Plus the leaves on A) are very dark, which could be genetic, but could be nitrogen overload. Starting to wind-down on the feeding as I near harvest. Tricomes are still clear, but there are a few hairs turning orange. My current guess is that A) will be ready in roughly 3 weeks, which is perfect timing to lower nutrient feeding.
