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.
@gottagrowsometime
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.
Hi, so I'm going to be dropping my seeds soon and have been doing my homework on common problems that might come up. Looking back I remember seeing something and luckily I bookmark everything that's worth holding onto. So, t could be phousphorus issue, take a look at number 5 of the list of most 12 common leaf issues. Hope this helps https://budverde.com/marijuana-leaf-problems/
