I am not new to growing by any means. The thing is I have always grown in soil. I recently started using aeroponics. I am having problems already. First problem was over feeding. I had my ppm at 800 then I made it 1000. Then my plants started yellowing and drying out. I flushed and ran ph balanced 6.0 distilled water with ppm around 0-50 for two days and they started growing again.

My plants are about 8" tall or so and have a decent amount of leaves. My ppm was changed to around 300 after flush and now some are growing twisted like, yellowing, and growing really slow. I was keeping my PH at 6.0 but I have done a lot of studying and figured around 5.5 or even 5.2 is better?

My problem originaly was over feeding, then I thought it was underfeeding so I raised it from the 300 to 450 and now I think 450 is too much . . . .

My question is what should my ppm be at right now? What is the perfect ph?
