Yellowing and light green leaves
Hello growers! My AK has been getting some yellow leaves, big fan leaves and small new leaves at the bottom, and looks less dark green. Is this a deficiency (looks like nitrogen but I don't want to give it even more nutrients) or is it just self defoliating? Any ideas?

Yellow/brown leaves
Noticed a brown/yellow colour starting to appear on my leaves. I don't think it's from the light being too close, so most likely too much/not enough nutrients. Any ideas?

Is that yellow on the cotyledon leaf normal? 2 days post sprouting and that one had helmut head the first day. I was able to remove seed pod by lightly lifting the edge of it with tweezers.

Deficiency or Nute Lock?
I was a told a week prior I was feeling too much. So I stopped. I left town for 4 days and came home to the current photos. One looks like nitrogen deficiency, the other looks like calcium deficiency except I've fed 1tsp of tiger bloom, .5tsp of Cal-Mag and big bloom last week.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Lockout during transition
Just a random question. I'm growing in a tent using coco and perlite. How do y'all keep your plants from getting nute lockout when they go from veg to flower? I seem to have this problem with every grow, no matter what I try with them. Thanks for any tips. โ๏ธ ๐ ๐ฑ
