Hello ladies and gents I’m having a prob with my ph I’m growing in gaia green living soil optimum ph is 6.2-6.8 I was watering with r/o water but realized it has no alkalinity upon doing some research after I tested my soil ph with my blue lab soil tester and my ph was 5.5. so I watered with 7 once and 6.9 another time and tested my soil ph again today and it’s 5.7. my plant looks ok but I can see some leaves being effected looks like magnesium deficiency, how can I counter this I have blue sky organically ph up and down but haven’t used them cus ph of water before it goes in the soil is great plz help.
Did you lime the mix? Myself, I use dolomite. Not only for pH buffering it provides, but it also takes care of Mg issues at the same time. Wet
