thank you for all the replie. I do have a ph tester and i keep my ph at 6.0 -6.8 (judging by the color ) I guess i will flush it once more to see if it corrects the problem but if it does not correct its self then will this affect my yeild any? also when i am flowering (now) what is a good nutes build? Right now i am as broke as Nancy Caragens leg so i may have to resort to the ole home depot or lowes stores any suggestions?
