first time w/ hydro -ph or nut. prob?

Hey guys, this is my first hydro trial, its going pretty good so far except for the bottom couple leaves are twisted and now have some spots on them...the twisting looks like ph imbalance to me but im still a newb so any help would be greatly appreciated...I am also going to continue posting new pics and comments throughout this grow..thanx

nutrient burn? areyou over feeding? are you testing your pH?

what is the pH? if you do not have a tester, you should drain your reservoir and fill with distilled water and letit run for 24 hors.. w/ no nutrietns... during this time, you need to get a ppm/pm meter..

ya i dont have a tester yet...i think i added too much nutrients the first time...the leaves started twisting like that so i changed the water and only put the "mild" dose in...it seems to be helping a bit w/ the newer leaves but i'll put some fresh water in there and get a ph test kit tomarrow..i'll keep postin...thanx for the help
