What's going on with my plants - First Coco Grow

I don’t understand what’s going on with my plants. I’m using fox farm big boy pants coco with perlite. Feeding General Hydroponics Trio 1tsp per gallon and 1tsp of TPS Calmag with no added nitrogen and 1/4 tsp of Recharge and a few drops of a root stimulator per gallon from GH. Is this a calmag deficiency? I don’t understand where I went wrong. I generally keep ph at 5.8-6.5 and am using an autopot system that isn’t hooked up currently to the res. One plant also has the “claw” effect going on which tells me it’s nitrogen toxicity… But only in the one plant. Otherwise I can’t figure out what’s up with the spotting and light colored leaves. Any advice would be appreciated.

Happened to me to I as well am curious
