I was topping off every few days about 8 gal at a time, from what I've acquired from this site and my local hydroponic dealer, I have been under feeding and adding too much cal mag. Apparently I dont need to run cal mag with tap water?? My ppms were too low and ph remained around 6.0
So anyways I cut early and cut my losses. I will be restarting with tap water and base nutrients only with a much heavier watch on my ppms and ph.
What is everybody's recommended ppms for aeroponics veg system, I started at 450 and noticed I saw yellow leaves towards the bottom and slow growth, raised to 900 ppms, and in two days I've added a gal per day and I'm at 695 now and seeing better growth, but would you add more or remain the same??
