Leaves turning light green -- yellow (after 12h day/night rhythm)
Since I started with 12h daylight/dark rhythm a lot of leaves started to turn yellow (older and lower ones first, some branches turned red). What I did: PH value=6.5. I added CalMag--no effect. I flushed the soil --no effect. Do you have any ideas? Thx green thumb-friends 👏

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
Ich habe 2 Pflanzen in Zelt und eine der Pflanze zeigt ziemliche Mängel. Viele Blätter sind mittlerweile gelb mit braunen Flecken. Die andere Pflanze hat diese Mängel aber nicht, beide wurden gleich gegossen, etc. Ich habe vor ein paar Tagen DolomitKalk und Worm Casting benutzt.

Yellowish spots ? Magnesium Deficiency ?
I noticed that on some leaves (not the new ones) there were 2-3 yellowish spots. And on a large leave, a point that turns brown. I thought about a small deficiency in Magnesium?

Yellowing and Reddening of older fan leaves
I’m experiencing a lot of yellowing that progresses into dark red blotches. I suspected a possible cal mag deficiency but after upping the dose multiple times I’m still having issues. Any recommendations on possible causes/treatments? Temp stays between 74-76, humidity around 60%
