Leaves curling down with brown leaftips?

The root's are not getting enough oxigen, give more water through the fogger and a lot less with the stream hydro system. Those ppm's don't ring a bell with me, I always work with EC values.

Spent $4000 made the switch from dirt, right past hydro to enviroponic growing. by that I mean aeroponics combined with hydro. just started first set of girls about ten days back. having a couple of issues though. went through some sort of apparent bug problem, as the leaves look munched. i treated it and seem to be gaining the upper hand. now i have leavescurling down strongly and new growth is contorting. two different strains, similar problem. I am going to my room to take pics of both the bug damage Rating: 5
