ill check my PH more often. I usually use 2-3 drops of PH down per liter of solution with tap water and I estimate my min/max PH is 5.0-6.0 for most my solutions but I'll get some more test strips so I can be sure.
What is a truly acceptable PH before it starts to affect the plant?
If u can keep it between 5.5 and 6.5 u won't go far wrong, it's a personal preference that I keep mine 5.5 to 6, I like to aim for 5.8 as it works for me,
Whats your medium? If its inert medium like coco coir, hydroton, perlite or rockwool, you need to provide secondary nutrients like calmag. Soil typically retains the calcium and magnesium but inert mediums do not. Let the medium dry out (soil first two inches dry)(inert when presence of dampness on top is gone) then give a good full feeding. Your PH'd water+nutrients+calcium magnesium supplements. gotta make sure your ph is right though. buy a 50 pack of pool test ph strips there like 5$ and they usually read between 6.0 to like 8.0. aim for just a bit lighter than the lowest indicated ph on the bottle
Yeah you def need to add the cal mag or trace elements into the feed solution. Some cal mags want ph of water to be 7.0 but always follow hydro rule of using 5.5-6.0. Post some pics for more info.
just water,ph adjuster, nutes a+b, cal mag and boost dont use trace if ur using calmag
