powder mildew and ph

  1. J

    Fourth week and the hairy white pistils are turning yellow!

    I'm growing hydro, using rock wool and have a tent...My plants are in the fourth week of flower...I've used aqua flakes a and b... A friend, who is a grower for many years, says that he doesn't ph his water...mine is high (ph) and I stuck with his advice.... now, the leaves are twisting upwards...
