Do you have an EC or ppm meter to measure the runoff ec? I'd drop back the feed to half strength and feed with a descent amount of runoff.

I find it almost impossible to mix small volumes of GH without an EC meter. Perhaps the solution is too concentrated but when I look at one of your pictures, I noticed a residue on one of the leaves. Sometimes a leaf or two get similar spots if the solutions gets on the plants when I water.

Coco is a very forgiving media to grow in but you would probably need to add some CalMag later. Except for the spots your plants look healthy. I wish you good luck with your grow!
