Early signs of Calcium deficiency?
Coughy
started grow question 6y ago
See a deficiency here? The whole leaf is very mildly spotty, like just a shade off... seems to be getting worse but very slowly. I had to filter the pics I took, were over exposed.

Looks a bit like the marks left from Ph fluctuations on that 2nd pic other than that I can't see anything abnormal

Spots of concern on leaves, any advice?
Spots on leaves showed up, just a few leaves not all. Seems to be around the nodes where I fim'ed her at week 5. Other strain in the room is not affected. Any thoughts? I use a spout pitcher to feed them, I originally thought it was nute burn. Blue Cookies Fem.

Trying to fix my plant after faulty pH meter...
Hey guys what do I think I should do.. so I had a pH problem and first I tried to fix my old one but it still didn't work so I might have given her a messed up ph again. So now I got a completely new one. What should I do? Give the girl a flush or some nutes to fix this?

How many times could/should I defoliate these Cobras? The Last photo shows a before & after which took place on May 31st and since that time, she has regrown to the point prior to defoliating. Should I repeat another defoliation? Far too many branches are shaded, again!

Is this some kind of deficiency?
Is this some kind of deficiency? There is discoloration around the edges of a lot of leaves on this KTF Orange, I’m not sure what it is from but the plant hasn’t seemed stressed at all.

Calcium deficiency?
Hello everyone, I need your help once again. I have just spotted some brown/yellow dots on 2 leaves of my plant. Did some research and looks like Calcium deficiency, but still wanted to ask you. If that's a Ca deficiency, should I add CalMag next time I feed her? Thank you ✊
