Any thoughts on these brown spots? They have popped up on a few leaves on the same plant (Amnesia).

Not sure, looks like damage from the fan or just a damaged leaf. Don't think it's a nutrient issue.

Brown spotting?
Hey everyone! My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean? I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

Calcium deficiency?
I recently bought Calimagic for my calcium fix. Prior to this week I have been using tap water for calcium. Is 2mL/gallon of calimagic too little? Noticed some leaf damage I believe to be calcium deficiency. Does she need more calmag? Thanks for your help all!

calcium deficiency?
I've notice some brown spot on one of the 3 Fat Bananas. I think it is due to calcium deficiency. I am not sure though, as this is the only plant of the 11 in the garden, which are having this issue . What do you think?

Lack of light or Cal-mag?
Some spotty leaves here at the base of the plant. The overall plant heath is fantastic and dense, haven’t done much defoliation so the bottom gets very little light. Is this a no light issue or calmag? I’m leaning towards calmag but the lower canopy gets very little. Advise?

End of Cycle or something to be afraid
Hi everyone, I think the brown leaves just reflect the end of cycle (WG started flushing 4 days ago, DSD33 today). I don't see signs of mold or something rotting, brown leaves do not detach, both plants show already some amber trichomes. What do you think?

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐
