Good Evening and thank you for stopping by to try and help diagnose the problem.

So I started a few plants in 3 gal pots with FoxFarms ocean forest soil and fed 0 nutes for the majority of veg phase. After several weeks, these plants looked very healthy with tight node spacing. I was planning to get ready to move to a bloom phase when I decided to transplant into larger 5 gal pots. When I did this I changed growing medium to a coco peet nutrient-less medium. So the container they are in now are 5gal smart pots with a core of soil surrounded by the coco medium. Upon switching containers I applied the hydroponic fox farm grow big at feeding recommendations. The plants have been fed every other day with tap water at pH of 6.2-6.5 ( Occasionally fed with minuscule amount of super thrive as well). I spray 1-2 times a week with neem or sm90 for mite purposes. (I have recently dealt with a aphid problem as well but they have seemed to go away within the past couple of days. They were a bitch to get rid of to say the least.) I am now letting them dry out a bit as they seem to show signs of N toxicity. I fed with a Cal-Mag folier spray last night (for the first time) @ 3ml/gal. So as of now I am only feeding straight water and cal-mag applications ever so often. The plants are showing signs of stunned growth (I believe from too much N) and burnt tips (I believe from too much nutes?? since with the internal soil medium is hot out of the bag) and yellowing from the bottom of the plant up, starting with newer growth. Any recommendations would be greatly appreciated. I may end up killing or cloning to death a couple of the rougher looking ones and re-potting the better looking ones and hope they come back around. Although if I can figure out how to properly treat what ever may be going on here I would like to correct them problem and flower out all of them.

Thanks in advance grow family

ps. the photos include 1 photo of plants before transplant into coco, and the remaining photos are showcasing different angles to help diagnose problems :)

The first pix indicate that the N is very high, deep green. Not sure what you have too much of but I would be flushing the crap out of those.
