Still have an issue. No pests that I’ve seen, Cal didn’t fix it, flushed res, lowered EC to half strength, problem continues. Temp 75 RH 50-60% PH stable at 5.8. I’m Stumped. Could it be my well/tap water? Spots are very dry/brittle

@braveheart, PH has been stable at 5.8-5.9 on the blue lab controller, very rarely doses tbh. I’m not so sure, UNLESS, it’s tap water related and the hard water is causing some unknown issue.
@hashy, I’ll give these suggestions a shot

Hi. Increase your hydroguard to 0.4ml/L. Increase your calmag to 0.5ml/L. Leave the rest as is and see if that stops it getting worse. Damage can't be fixed on old growth.

Looked into that possibility as well, one reason I flushed and added back half strength EC. Not so sure but I’ll consider it, I appreciate the answer. Stay tuned. Will give it a few more days.

Organic slow-release amendments...How does an excess occur? I thought that couldn't happen :-/While these gals are super healthy and look great (What do you think?), I'm looking for high-standard criticism/advice. Are these leaves too dark (Slight claw on certain leaves, N excess?)? Also see very minor tip burn. I'm using organic slow-release amendments...?Week 13

Defoliation during flowering and overall plant healthShould I proceed with defoliating this plant on day 28 of flowering? I am always a bit reluctant to doing this as I think it stresses the plant a bit too much when it is supposed to be producing flowers, but I would like to hear from you guys.Week 10
