[NucksNugs]

might I suggest reading this lovely book":

Thanks

when you do so, please remember to turn off your lights (if they are Blurple/HPS) so the Foliage isn't washed out or unable to be studied.

Medium is HF and I don't have a good ph tested but last time I checked it was a tad high..upper 7's

PH is not a linear measurement. It is measured on a bell curve like earthquakes. .1 can be a fair difference. 1. Is a monster difference.

I dumped several years ago due to quality control issues. Was having a pH drift mid flower on every run.

You need an accurate reading on your soil, and a printout of your local municipalities water quality.
Here my water is bad enough that I can't use it for growing anything... yet they expect us to drink it.

Best bet, jump into the infirmary, and fill out the questions. Could be a ton of things unrelated to what we're guessing at.
