Hi Sora, This is typical calcium deficiency symptoms, but since you're feeding calcium that means you have a calcium and magnesium lock out. you need to reduce the amount of calcium as much as possible then start adding it again but less this time. Hope this helps ! 🚀

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!
