Kush n' Cookies CBD - First grow

First official week of flowing, though I flipped her a few days ago due to height constraints. To recap some goals from late last week, I'm going to aim to keep my light at around 13-14" away from the canopy. I'm still trying to keep nutrients on the low side, and it seems to be working out well so far. I know she needs to be pruned pretty badly; I'm aiming to do that around when she's done stretching in a couple week (I hope). Everything is going well so far, aside from some minor clawing at the tips. I think I might need to reintroduce the oscillating tower fan at some point to keep air flowing through the leaves. Day 36 F(4) - Minor clawing, but nothing else to indicate something's wrong. Day 37 F(5) - Nothing noteworthy to report. Day 38 F(6) - Noticed a leaf fall off while I was watering. Went around and plucked 8 or so more sickly looking leaves. All bottom growth. I know the older fan leaves are supposed to yellow and fall off during flower, but I can't help but feel like this is a little soon, and there's something else going on... I might continue to mess with the water. I've definitely been seeing I'm feeding considerably less than average in coco. Day 39 F(7) - Switched from transition to early bloom following my feed chart. Reintroducing calmag. Feed mix came out to around 1300 EC. I think before when I was playing around with the water I was messing with the root zone EC too quickly. This time I'm going to gradually move up to full strength feed. I've been watering feed at 900 EC. Today's feed was 975 EC. - Pruned a lot of the dying leaves and bottom growth getting zero light. I also removed a handful of shoots that were also in the dark and had no chance of reaching the canopy. Day 40 F(8) - Watered at 1075 EC Day 41 F(9) - Watered at 1150 EC - RO filter purchased! It should be in use in a few days. Day 42 F(10) - Watered at 1200 EC, now up to full strength. I really hope she stops stretching soon, I only have about 8" left to raise my light to!
