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.

Could someone help me to identify the issue my plant has?This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

Leaves turning yellow with brown patchesI noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

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.
