Those leaves looked fine, fine enough to leave on at least. What was happening there was the plant was cannibalizing itself. It's not getting enough of the right nutrients so it transfers what it needs from it's old growth to it's new growth. You should have left the leaves on because now it may start taking what it needs from the next oldest leaves.
You said you're using RO water with GH bloom and ph up. First thing you'll need to add additional calmag. GH bloom isn't made for RO water.
Do you have a water softener? Why aren't you using tap water? Tap water contains many micronutrients that probably aren't included in many 'all-in-one' ferts.
