So this is my first hydro grow. I have 6 critical clones that I put under a 150 HPS last night. They look like they made the move well and appear strong. I have the lamp about 8" above, pH is about 5.9 (I have been lowering it when I see it above 6.2), water temp is about 79, air about 81, ppm running about 350 (tap water was my only option at this point), and I added a 1/2 strength root 66 and sugar daddy from techna flora. The only prob I can see is a little yellowing on some tips/edges. Is this normal adjusting from their previous home? Any suggestions moving forward for a successful first go? Thanks.
