can be a cal mag deficiency, but before check your ph (has to be something like 5.8) and the power of your light (too close/ too much power etc)

I think it was a cal mag and everything else too. I believe I was just under feeding them. Thanks for the help

Calcium or other deficiency?
Is this a calcium deficiency? Brown speckles on only 1 leaf but some other leaves gave mildly upturned edges. I had what I think was a magnesium deficiency a week ago and added calmag.

Leaf Mutation After Topping?
So I topped this 10 days (ish) ago. The leaf mutation, I'm wondering if it's actually where I topped it. What do you think? I think cut it pretty damn clean to be honest. I just want to figure out why the leaves are this way. 🍃✌️

What is wrong with my plant?
My Blue Cheese Autoflower newest leaves are floppy kind of and the tips go a darker green and there are small browning parts. Pictures are available for reference plus my grow journal. I am hoping all I need to add calmag but can anyone tell me what the main issue is most likely?

Cutting fan leaves
Just cut my fan leaves 😳 the stems we’re turning people, if I’m not mistaken it’s an early sign of an old leave that’s not as efficient in the photosynthesis? and it was covering the new growth, Or should I have waited?

Leaf spots
Hi guys. These spots have formed on the lower leaves. Is it a cal-mag deficit or maybe is it due to strong airflow? Also, are they already big enough to switch to 12/12 light or give them another week? Thanks!

I'm hesitant to defoliate since this is my first auto grow but the blueberry is damn bushy the tangerine dream could use a touch up too. Would you remove all the big fan leaves, half of them or what would you recommend? Tucking/tying down leaves is no issue if low stress is key.
