Hi guys, and thanks for reading
It's my second grow (previous was successful soil)
Swapped over to amazon aeroponic system with 8 clones
Absolutely can't figure it out! Roots are healthy but plants don't seem happy. The leaves are curling and don't recover for 3 weeks
Ph is 5.8 , ppm 450 currently, tried 550 and 350, no change
Replaced water and made sure all Params are correct
Looked at root system and one root filled hole that allows water to go back to reservoir but again didn't change things much
Light is hps 600
Don't know what else to try ?
On week 1 we had a day where i messed things up and ph got down to 4.0, which I slowly brought back to 6.0 over next few hours. 3 days later leaves started to curl , and never recovered from it despite our best effort
Any ideas ?
