Yellow spots nute difficiency? Light burn?
I noticed spots on both LB and NL that seem look like nute deficiency, my best guess is cal. I will check pH of soil runoff at next watering to eliminate lockout as a possibility. I've heard FFOF soil runs out in about 4 weeks, maybe that? Light burn from water drops on leaves?

Anyone know what's wrong with my girl?
Can anyone tell me if this is going to effect my flowers? Should I cut these leaves out? What can I do to correct it? I left a pretty good description in week 7 of the battle with this plant.

Is this light burn?
All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance

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?

Maybe someone can tell me if I should or can defoliate The BlueDream No 1&2 Cause the leaves cover a lot & each Day the girls grow more & it gets more difficult to LST or bent the leaves somewhere & idk what’s going on with the BlueDream No.3 I did some research & I thought it might be CalMag deficiency so I add 1,5 ml GHE CalMag to 1L water but the problem with the leaves is still there ( see pic BlueDream No.3 ) I’ll be thankful for any advice & help !!

What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Seedling leaves are discolored and starting to curl
Not sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!

Hallo liebe Grower, bei mir ist BT 21. Kann mir jemand sagen warum die Blätter der Blütenstände so „Neongrün“ werden ? Liegt es an Nährstoffen oder zu viel Beleuchtung? Die Lampe ist recht nah dran da keine Luft mehr nach oben ist Wäre super wenn jemand einen Tipp für mich hätte
