IDK about Hydroponics but it looks like a few deficiencies and isnt 86 degrees a little warm?

The addition of the hydroton to the grow media is part of the problem. The hydroton will have an even faster dryback than the pure coco. You need to water much more often. You are at the beginning of locking the plants out because the media is drying out and the salts stay in the media that the plant does not absorb. Meaning every time you water you increase the PPM's/EC of the media. To fix, start out flushing each pot with 3 times the amount of water the pot holds. Straight water. Right after you finish this task water the plants with 1/2 PPM/Ec value of what you have been previously using. The media needs to stay wet at all times. This is your largest problem.
