started grow question 3y ago
The colors of the leaves make me think. I don't give a knock during these weeks of bloom time. Do you think this is a lack of calmag? or this is normal:)?

Leaves curl up and yellowing
Beginner question, as usual (first time growing anything in my life tbh). My 2 plants don't look too healthy, especially one of them. Leaves curl up and yellowing (or not, I am not sure). What am I missing? Thanks!

Blätter gelb und fallen ab Blütewoche 9
Aktuell machen mir meine Pflanzen echt Sorgen, viele Blätter werden sehr schnell gelb und fallen von allein ab obwohl ich bei jedem gießen Dünge. Sollte ich noch mehr düngen und häufiger gießen? Die Buds sehen soweit gut aus nur sind bis jetzt immernoch mehr weiße Haare als Blüte

Yellowing leafs and dying tips
Hello ! In the last few days I founded that some leaf started to yellowing and burning on the tips . Maybe it's all due to the flowering stage but I'll be more calm with your answers that are always interesting and helpful even if the platform allows only one to be selected.

Do I have a deficiency problem or am I ok? 3 lower leaves on both plants started with the tips browning but now the leaves are going yellow. None of the newer growth has been affected but the 3 leaves seem to be getting worse. See pics in week 4!

Is this Stating something or is it paranoya
I had a few leaves that were turning yellow, but they are lower leaves that are slightly yellowish on the outside, generally the plant has become a little lighter since it started flowering. Am I worrying too much? pictures were taken directly in the morning

Leaf discoloration and curling
I’m not sure what’s wrong but all my other plants are fine. It’s in pearlite and peat moss and I’ve been watering with ph balanced water. I did use a very little bit of half strength dyna grow but I only did a little squirt.
