So looking at the last 2 pictures, what do you guys think? Lack of nitrogin or magnesium? Or is it because she doesn't need the big leaves anymore? Thanks for answering!

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Upward curling leafs, burned tips, 2nd week of flower
So I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/. And some fading on some lower leafs. Using biobizz roughly 10ml each Any ideas

BT21 Probleme?
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

Hello growers! I wanted to ask if the lower leaves turning yellow and dropping is normal? 2 leaves are down and I know that's a normal behavior but another one is turning yellow and I just wanted to check if this is normal.

Bottom leaves yellowing at beginning of flower
So my plants have been flowering for about a week now and the lower fan leaves are yellowing with brown spots. Should I be feeding them more of the flower girl I’m using or is this a deficiency of a specific nutrient? (following dr earth feeding schedule designed for cannabis)

Leaf started yellowing and growing a weird shape. Too much light? Too much water?
Issue evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. They are also making a weird shape! Clear images of this in the post above. Tons of details about conditions/ environment. What's going on here? Help!!
