9 times out of 10 this is due to lack of Calcium.

There's no doubt in my mind that this is a Calcium Deficiency, which can easily be fixed with a dose of Cal-Mag, but the damaged leaves aren't going to get better so you might want to remove them.

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Fungus or deficiency?I have these gals growing outdoors and have a few leaves that look like this. Appeared after multiple heavy rain days. Applied nutrients yesterday so I still need to wait for the results. Is this a sign of fungus or deficiency?

Please say it ain't bud mold :(Noticed a brown spot on my center cola last night. This morning it progressed so I removed it. I'm noticing browning on nearby leaves. It may be nute burn (I have been heavy on them), and I did recently increase light intensity to full two days ago, but my temps are ~74f. Pls no!

So in the last 3 pics from Day 22...am I seeing a calcium deficiency? She gets tap water, which I was hoping has sufficient calcium. But now I'm thinking I might need some Cal/Mag. Is she hungry for calcium?
