so this problem looks like a ph problem to me. but ive been fixing with 5ml of apple cider vinegar per gallon of my 8.2 RO ph water to make it 5.8 (pure coco). and i have a meter. does anyone have any ideas? ill list whats goin on... 400w HPS, 2.5x4x6, various strains, multiple stages of flower, temps no higher than 90 at most. per week: 3ml House&Garden (3/4 strength), half strength botanicare cal-mag. my maximum EC that i have given is 1.86 microS, but i usually do 3/4 of that. my RO water is .03 microS. i really want some green plants! i have had a mildly yellow plague for quite a bit now.
1st pic is some plants in the back just out of veg. they usually dont turn yellow until flowering. Girl in the front has a month left
