I’m currently in week 3 of flower and I’m noticing these orange/rust patches on the leaves. The temps r 78 and Rh is 45 I’m in coco perlite 70/30 ratio watering at 5.8 ph using nftg line with calmag recharge and mammoth p . I flushed this morning with Phd water then water at 1/2 strength nutes but more spots showed up. I’m trying to learn so any input would be very much appreciated
