Anyone able to diagnose this? (GOOD PICS)

Im no botanist but I think your problem is due to lack of sunlight.
Sun=Photosynthesis=Pigment in leaves. You are losing alot of pigment I see. I u think this is bs please disregard. only tryna give my 2 cents.

Early in the thread someone said to pick up both pH up and pH down. I would disagree with this statement. Depending on your tap water will determine what pH product is correct for you.

Example : My tap water comes out at 7.0 or 7.5 depending on the day. All I need is pH down. Should I decrease my solution to far all I have to do is add more tap water to bring it back up again. Simple as pie and saves you a couple bucks in the process.

Also take it easy with that pH adjusting solution. Usually all I use is a half a cap full and that is usually adequate enough to drop it from 7.5 to 6.0-6.5.

So if ur Nutrient Solution needs raising u water it down!?
Im pretty sure he mentioned it earlier cause its alot quicker/easier just to add a few more drops to correct PH...
...is for me!

I balance my pH before I add my nutrients. My nutrients do not change my pH values. Maybe yours do, I don't know.

Your best bet is to just chop it down and start over. Haha... Just kidding.

one of my plants did that....i decided it was manganese def..or nitrogen....luckily my fert to add was the only one that included both...so i dodged a bullet added more manganese...plants recovered and look at em now!
