I ran into issue on my autoflower around Memorial Day my ph spiked, I feel like i am still doing something wrong

FFOF, I was doing humbolts secret then I switched to FF trio I flushed her after I saw this then gave her recharge she was running off 8.3ph but the recharge brought her down along with me giving her 5.8ph Ro water ppm was reading low after the flush so I dosed her with about 1200 now she is up to 1600ppm

Hi, you could be right about PH causing this.

What kind of soil is she in and what have you been feeding her?

Do you have the PH and PPM of your run off?

If you have taken care of the PH issue then the problem should stop spreading. If not, you may want to flush her with PH'd water to get rid of any salt build up and reset the soil PH.

Good luck
