Ok bare with me im new . I have a bubba kush plant in flower 3 weeks was seeing issues a week in & talked to our local shop guy and he says I was over ferting so I cut back as he recommended. I am in DWC using air stones I keep my water temp at 68, pic below shows what he said was over ferting. I was mixing as the label called for and after mixing I was 720 ppm he said I should be no higher than 480 as my water out of tap is 80 ppm sorry I had no ec info still not getting that part. I change my water once a week check my ph once daily I have changed water twice since I lowered my mix & now I have a new issue of yellowing, pic's included Indoor Tent with fans, Led light Room temp average 70 night 75-80 day Normal humidity for my room 44 give or take As of tonight's check my numbers are. PPM 411 For EC my meter reads 0822 us/cm , im still lost on this . PH 5.6 If i missed any needed info or my post it to much please let me know.
