imho, coco carpets keep things too wet. You don't need calmag with FN, and at that size your plants can handle more than 600 ppm. I would dump the calmag and koolbloom and finish up my stretch at about 800ppm of just the FN grow. Right now your ppm's are high but full of junk.
Also, if you dump those solid pots for perforated ones, the roots will be able to grow out and not rot or be rootbound. That will also let you flood more often.
If you need PH up, try Barricade. It's Potassium Silicate, good for stronger branches etc and doesn't have any nutes.
Hope that helps
