Your cabinet looks great. Your plants are over nuted though.
Pure FFOF has plenty of nutes almost too much for small plants. I would flush them out and just water for awhile. I like to mix the FFOF with sunshine mix #4 50/50 it's a great balance and still leaves room for extreme nutes. The Fox Farm schedule is powerful start out at half stength or less and get a feel for it.
I did a side by side comparison with four plants from seed using FFOF and Sunshine mix #4 (which is a soilless medium that has no fertilizer) in the Sunshine mix I used the Fox Farm grow big soil and big bloom. The FFOF plants had too much nitrogen but stayed really stocky, the sunshine plants were a little more stretched, not much at all, but the stem was wider and the roots ran deeper.
This is what brought me to the 50/50 mix. Check out my log in my sig.
