From the photo it don’t look like a big issue looks to be a burn from water or moisture sitting on leaf in the light

1 out of 3 doesnt do as well as the others
Im just wondering why one out of 3 plants, does not perfectly well while the others seem doing awesome. Can it really differ from a strain that it shows signs of light stress or nutrient burn while other plants seem to do well with it? I added 3 pics, 1st one showing the meh one

Plant #1 started out last week with light colored patches on the leaves of the first 3 nodes. The lighter green patches turned into a rustier color. Rest of plant looks healthy. Also all other plants aren't affected and are growing lots of branches, but #1 is not. Any ideas?

Brown spots on top leaves - nutrients, light or something else?
She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help

Bugs or no
Do new cannabis leaves sometimes have defects or missing pieces? Mine seem to have a few missing spots and I’m wondering if it’s bugs or something to keep an eye on?

Slight browning of upper mature leaves
Mid week 8 just noticed this color change on the ends of a few fan leaves near the top. It is only noticable on the upper most 4 mature fan leaves. Nothing on the new growth. Nothing on any lower leaves. Any ideas?

Defoliation of Fan leaves. The COBRA's growth structure is very tight nodes with large, Indica-type fan leaves. The largest one (3rd pic) has tripled in size from the last photo. I have been bending the leaves under side-branches. Can or should I cut them off to allow light in?

Hey, anyone got any idea or clue what's going on?
I thought it was a manganese or iron deficiency from an early watering with high pH. Though I've fed/watered my other 2 plants pretty much the same stuff but she seems to be reacting really poorly. She seems to be getting better slowly.. I think. Thanks for taking the time. :)
