thanks for all your help . i droped the ph down to 6.5 . the ph tester kit says that 6.5 is all good . i just flushed the system with clearX , and i just put in a buble stone . also i forgot to say that i sprayed the leaves with water (from the tap) ,ya ya i know now that it was not the best thing . all the new leaves that are comming in are looking good and green .
