I have tried two grows. Both with Fox Farms nutes. Both times at week 9 my plant has died. Followed all the instructions. Flushed when it was time. Same result. Add the "Cha Ching" and the next day. Browning yellowing dying leaves. Should I go w/o the Cha Ching or switch to different nutes? Wasting my time and $. Grow outside no problems. Hydro. Nothing but problems after week 9. Thanks.
