Hey there, don't know if your still reading this but I use cutting edge solutions and it's pretty touchy. First of all they tell you to not ph the ferts after you mix because it will be low, the chemicals actually gain in ph when they break down. Also it's recommended to ph up them to 7.0 before adding nuts because it drops the ph really low. You clearly have nute burn(too much), they won't need mutes for another week or 2, they'll get their bytes just fine from the soil to begin with. Clawing=nute burn. By now you probably have a ph problem too and should be testing regularly. I had the same problems. The plants are great until you feed them nutes then they slowly start to die, just flush them with water a few times and give them nutes in the 3rd week next time.
