Week 4 flowering.
4 girls all treated the same other then I defoliate 2 of them (on the left side) and left the other 2 alone. The defoliate ones are fine but the one on the back right looks rough, the leafs are a light dying green. And just turned a few hours ago. They are all under the same lights and received the exact some nutrients.

You shouldn't defoliate that early. Sure it's week 4 but expect a longer flower time at this grow rate.

Your yellow leaves are not that bad/deadly to plant. I'd move it to a different part of the grow tent, cut off leaves more than 3/4 yellow, and hope for the best.

It looks like ph problem, What medium is it? Cal mag ?

Definitely need to know the medium. I'm not an expert, but it looks like a potassium deficiency to me, which I had a while back. Mine was caused by a pH problem which led to nutrient lockout. Apparently can also be caused by stress though.

This op clearly communicated that the medium is grow stone net pots in DWC with same nutes in all 4 buckets.

Only 1/4 plants is effected

I concluded the factor could be something about it's place in the tent, such as air flow amount.

Op, Are these from seed or clone? Same strain?

It is nutrient related. Looks like K lockout with a side of N def. Either your plant is feeding much more than you are giving it or nutrient interaction of some sort.
The defoliated plant doesn't have the reserves like the other does because you took them off.

Ah, I totally missed the DWC buckets in the pictures I was so focused on the leaves. I agree that even if it's a deficiency it's probably because of placement or some alternative factor like stess causing a lockout, not an actual lack of nutrients or pH issue then. Unless it's a different strain or just a really heavy feeding individual I guess.

I know this is a confusing chart but not really once you realize how to read it. K can be locked out by having too much Calcium, Nitrogen, Phosphate or Magnesium. Any chance you have overloaded one of those?

If you hadn't defoliated as severely the plants would have fared better. Until you do a few successful runs with no issues don't defoliate.

I'm seeing some variety in the plants. Some are more Sativa dominant and some more Indica dominant. It seems the Indicas didn't do as well so my guess is they were more susceptible to the nute regimen and I think therein lies your problem. Try letting up on the rate and although it wont help you this run it may help in future grows. Really, Cannibis is so finicky about being fed too much stuff. And so you just burned them. Not much but between the burning and the removal of the plants ability to photosynthesize it was double whammy.
