"...I'm watering once a day..."

and there's your problem. Coco is a different animal. You're not watering them as you are fertigating and needs to be done 3-5 x's a day with runoff about 10-20%

Go back to the lower amount of nutes but water (fertigate) it every 3-4 hours every day. Once growth is back you can slowly up the nutes but keep 3 x's a day minimum.

I don't agree with you. Lot of people grow in straight coco and watering once per day with great results

I currently have 3 Mother's Milks in 3 gal pots 8' tall. A 4+ footer in a half gallon nursery pot. I don't know anyone watering once a day with results like that
