ph'ing,, by my experience, is most important,, and i have had oh so many issues,, least of which is a wonky el cheapo ph pen,, throwing things off by .3 or .4 on the ph scale can cause such grief,, and by slowly adjusting , itr simply takes forever to correct, and dial it in.
a work in progress for me,,
but bluter is hempy, like me, and 5.8 is close to optimum, i am currently using 5.9 with a suspect pen,, tho now i have calibration solution and calibrate often,, a big improvement
Good thinking!
The pen will get you close, but the leaves never lie
