Started growing in aero about a month ago & started giving them nutrients about 3 weeks ago. Growth took off quickly and near the end of last week I had to keep adding ph down to regulate it but figured since nutrient levels were very low -300ppm-maybe too lo for ph buffers to help much. Changed out the reservior Friday night & mixed up nutrients to 500ppms and it's the same thing- I read that aero growers like Stinkbud use very high ppms as compared to DWC grows like I am accustomed to but worried about nute burn...should I jack it up to 1000+ ppms now that the plants are getting a bit larger? Do plants in aero use up the nutrients really fast due to the abundance of o2 they receive? Or could there be some other issue affecting ph?
