You don’t say anything about your feeds. It appears developing potassium deficiency and not nitrogen toxicity. But guessing without the specifics.

I went with the cheap black and yellow PH meter, Milwaukee's Best. It doesn't work right.

The bluelabs PH pen I have is stable and works consistently. Although the buttons went funky on me but I recommend.

I have a nice ph meter, meant ec or ppm meter, thanks though.
another one is doing this now, I just gave them all 2 gallons of water today, last feeding was at transplant 4 days ago and they where watered and fed until run off then.

Use litmus paper for pH. It’s more than adequate for our purposes. Use the money you saved from buying a pH meter to buy a real EC meter. And never consider coco.

Apera do solid EC meters too, their cheaper one without replacable electrode is fine.
