measuring ph has been a problem, had a lot of 'fines' in water, very murky, so i've been flying a bit blind
normally use ph drops which need water that's not too muddy
that said, my plant seems to quite healthy, mostly seeing a bit of curl, and some roll on the upper leaves of the cola
watering about every 4 days, got a little wilt at 5 days, that was my dry limit
i did dolomite the soil on mixing, hoping that has kept ph in a good place
