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

First grow with autos, are these growing too slowly after a week?
It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week. Are growing slower than they should be, and is the discoloration on the 2nd image a cause for concern?

Which deficiency?
So I've asked before if it was a magnesium deficiency on the GC and got confirmation based on the early pic, but now I'm starting to wonder if it is? Buds don't seem to fatten up either. Maybe calcium or potassium? Lights too strong? Overfed? Shouldn't have given Vega just flower

Damaged Leaf - Problem Identification
I know it's probably nothing to worry about since this is my by far best growing plant right now, but it doesn't really look like a mutation, more like damage or something. This is the only leaf i encountered, just wanted to check if anybody knopws what it is, hopefully no pest.

Been struggling with leaf issues for weeks. Initially thought lockout due to N toxicity. Plants improved after flush in Week 7 but then promptly started worsening a few days ago. Is this a continuation of a lockout issue? Would you feed? Flush? Advice is welcome! 🙏

What could this spot on the leaf be? It has been visible for the last couple of days and it's been growing WITH the leaf and not independently.
She has this one spot on the leaf. It is only on the upper side, meaning if i look underneath the leaf there is no such mark. I have no idea what it could be. If it indicates some sort of problem then I would like to get it under control before it propagates any further.

Copper spots on mature nodes. Day 64
I am seeing some copper colors starting to come out on some sugar leaves near my more mature bud sites. Started today on day 64. I have been following fox farm nutrient schedule and watering every 3rd day with PHd after adding nutes at 6.2. Is this normal or a nute problem?

Slight accident last night to one of the cookies. Me and my thunder fingers pretty much snapped the top off while trying to support her. Is it game over for her? Looks like a clean break and she's still standing. Will she grow asif I topped her on purpose?

I was late watering one night last week and she was looking wilted, then 48 hours later, she looked this like with all fan leaves wilted or dead and crispy and she isn't standing back up after watering. Nute-lockout? Underwatering damage? I always check nute pH. Thoughts?
