some leaves thin, curled-upward, browning edges

I gave them all a foliage spray yesterday and today of half-strength fish fert and B-1, and some Hydroguard to help protect the roots. I also added half-strength of B-1 and Hydroguard to some 500ppm/6.1pH nute solution and gave them each about 1/3 ounce right at the base. The rockwool cubes still have water in them, so I don't want to add any more than needed. Hopefully the foliage spray will deliver some nutes quickly, and the cubes will dry out further so the roots can resume their duty.
The Supernatural Brand Gro Aqua is 17-7-18, and it calls for 700ppm full strength. I started at about 350ppm, and recently upped it to about 500ppm as the kids grow. I'll be switching to their bloom solution soon, but I need to straighten this problem out first.
