Hey again

Room: 77deg F/65%rh
DWC, 5 gal. Buckets, 15 L water
Plants: all autoflower, various stages of development, all flowering.
Nutrient: HOG 3 part (grow/micro/bloom) basically same as general hydroponics, but with a little bit higher concentrations I think, Feed at about 3/4 strength of their chart
Additionally: Regent-a-Root @ 1ml/L
Hygrozyme@ 2 ml/L
H²O²@1ml/L(every 3 days)
PH 6.0-6.5 (usually drifts up)
EC .9-1.3 (usually drifts down)
Well water is filtered then uv treated. Comes out of tap about 140ppm/ph 9

Skunk:
2 weeks into flower, still stretching a bit

Any help would be greatly appreciated. Seems like all my plants end up with this issue, early to mid flower and am never able to resolve.

I am pretty sure it is Leaf Septoria. It is a fungus and here is the possible solution, I would recommend an anti stressing agent first though possibly if you have alot of pruning to do. https://www.growweedeasy.com/cannabis-plant-problems/yellow-leaf-spot-leaf-septoria#:~:text=Sometimes%20called%20“yellow%20leaf%20spot,bottom%20leaves%20of%20the%20plant.

I didn't see cal mag in your regiment. If you are running RO water it is imperative to add it. I use 5 ml per gal. There is a chance this might bring them back. If non RO water it would probably be less than 5 ml.
