Yellowing, end of wk 6, ideas?

Been watering using RO water, ph’d to 6.2-6.5, and using calmag/foxfarm trio/recharge, yellowing started maybe 3ish days ago, is this deficiency? Do I need to be feeding more? Do I need to feed less, and flush?

If you’re in soil then a ph of 6.2 is pretty low. I would recommend not PH’ing the water at all and up the feed rate if the base nutrients. Everyone seems to get hung up on PH’ing the water but in soil it buffers on its own so no need to ph unless it’s really low so I would say as long as your within 6.5 to 7.5 it’s all good. Most nutrients lower the ph to begin with.
The one yellowing looks hungry to me

Okay, I’ll try running a higher ph. My water comes in at 5.1

Yeah that’s crazy low. I would recommend not using the RO water and just use tap water going forward and cut out the cal/mag since the tap water and trio should have plenty already

Okay, I’ll try it out. Are my plants too far gone? Can I save them? I don’t think they look bad, but I don’t want the problem to get worse.

Smart to feed every other watering still, or every watering?

I would give them a couple feeds in a row then just a watering in between then 2 more feeds then water and keep it going like that. But you could feed a low dose every single time and be fine. Once the soil runs out of food you need to substitute it for the rest of their life so you may need to feed every time but I would start with 1/2 the recommended dose and give them a couple feeds and see how they improve.

Thank you! I’ll water them in a few and see how they do

Get rid of the RO...cal mag, all that junk. Get you some tap water and feed just "grow big" til the end. For soil I probably wouldn't feed every watering, maybe every other or every third at a moderate EC of 1-1.3. By doing this method, I've gone 11+ weeks of flower with zero yellowing. Most people are so afraid of nitrogen in flower, and are severely hurting their efforts.
