Not sure what’s going on with some of the new growth. Not looking great, the new growth on some tops are looking deformed and one of the tops is bending over like it’s dying off. is it a response to light/heat or a nutrient deficiency?
They are on day 73 from sprouts. I just flipped them into flower this week. They’re on day 6 now.
2 Truffle Knockout and 2 Mac N Jack plants.

One 2x4 tent. Electric sky 300 dialed in at the recommended light percentage @18” above the canopy as directed on the power dial. Two 2x2 tents with spider farmer sf100 in each. 3 gallon pots with Bio365 Bioall soil. The temps are 75-78° and I’m trying to keep the humidity around 40 but it’s been a little high since it’s been raining. I made some scrog nets to spread them out. The 2x4 tent has a second net installed to support the stretch. I feed them with GH flora trio, GH floralicious, and Mammoth P. Today I tested the run off after I fed them and the ph was between 6.59-6.67. A tad bit above the zone. Do you think this could be throwing off the nutrient uptake? Maybe causing issues for the new growth? Next watering is plain water that I’ll ph down to 6.2-6.3 to hopefully drop the soil ph down into the zone for the next feeding after.

I hope to solve this before things gets worse! Let me know what you think thanks!
