Hi the nutrient solution im using says ec 1.5, ive not been following there guide because of nutrient burnt and am running about 0.8 ec and im growing in aeroponics and this level seems to be working fine and im upto 3rd wk of flower, I'm just abit unsure if i should be using higher as everything i read seems to be higher. Added photo if it helps.

Very simple to find what they need in a recirculating setup imo.
This assumes you have a decent size reservoir:
If the ppms are dropping, bump them up. If the ppms are rising, lower them.
When you have the ppm's dialed in, they should stay about the same even as the nutrient solution is being used up.

Say my ppm is 560 the following day it is around 500 so ive been topping it bk upto around 560, so if im right from what your saying i should be putting more nutrient in until it stays around the same daily.
