About to do my flush and was wondering if there is a specific PPM I should have my flush water at? I know I should flush with about 6.6 pH'd water just didn't know if the ppk matters for the flush?
Soil pH needs to come down to about 6-6.2. And the ppm indicates a slight buildSo, gave them all a flush of around 2.5 gallons of water.

pH: 6.6
Ppm: 220
After flush, the collected water showed..
pH: 6.8
Ppm: 640

Up of salts which may lead to future lockouts. I don’t know how others do it, but when my soil pH was higher, I flushed with a lower pHed (6)/low ppm feed 250ppm(ish) 20% more than I’d normally water and I was able to stabilize my soil pH a bit. After that my soil pH was a constant 5.8-6 which was sufficient for my first grow. I had no signs of lockout, just a bit of heat stress. Wait for some other opinions first.
There may be better ways to bring the soil pH down and stabilize it better.

Oh, for sure! Want to let them dry out a bit before each watering. What do you think for next watering though? another jkust water flush or back to nutes again? I'm not a good judge of when they only have 2 weeks left so I don't know exactly when to only use water.I’d let the soil dry out a bit before watering again.
