As far as I know, Calmag is recommended for plants that we grow in a box under LED lighting :)

Yellowing of leaves Week 9
Help! Is it normal to have such yellowing Week 9? The buds are still green, but the bigger older leaves are quite yellow. Same strain different plant still very very green. Might be the difference between topping an auto and not topping an auto?

Why is one leaf yellow AND shiny?
Plant has one leaf that is yellow on one side, and shiny/dark and curling up on the other side? From what I've read those are 2 opposing issues (light burn or nitrogen deficiency/or toxicity) the others are pretty much uniform, Could this be from getting water droplets on leaves?

Calcium deficiency or overfed?
Hi. This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress. Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain. Thanks!

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.

Possible Nitrogen Deficiency?
Is this a nitrogen deficiency? I had a yellowing leaf or two at the bottom of the plant which have since dropped off, but rest of the plant is looking patchy now. I have just switched from fish mix to bio grow.
