Hi hgk thanks for the input mate.. I'm in an auto pot system and have been told to never flush a wick system? Basically because all the salts are supposed to come to the top. Also I have a scrog kinda thing going on so flushing wouldn't be ideal. I might just bang 50ltrs of plain PhD water through the res see if things improve?

i would try to at least see if you can get a little flush through into the valve well and test that and see what EC and PH are. those plants look to be on par to be an amazing pull and it looks like theyve been fed their fair share by the size of the buds I'm very curious to see what your run off would be.

ya like i said its good to note what the PH lvl was before pouring onto the plant so you can get an accurate read on the run off but too much buffer through a root zone can be bad. I've never seen issues but a super nerd who i trust with all things hydro informed me of this, so i trust it.

if the water is 7.0 PH going in and the run off is 6.0 then correct me if I'm wrong but wouldn't the PH of the plant be in the neighborhood of 5.0?
