Shade Leaf Spots

Below are two photos of a shade leaves, most my girls are big and strong. I feed them once a week (foxfarm [tiger, bigbloom]) I water with distilled water twice a week on top of feeding. I am 5 weeks into flower and on most of my leaves are getting spots. I cant seem to find out what it is. When i feed and water i give each girl 1/2 a gallon they are in 3 gallon pots with ocean forest. I have it narrowed down to either too little water, nutrient lockout, or heat stress. My space fluctuates from 67-90 degrees. The median temp is about 77 degrees. I should be adding co2 by week 6 (at that point I'm not sure if i should bother with co2, or should i?).


Any thoughts on the above would be greatly appreciated.
