Do you follow their recommendations or use less.Hey @Bill284, thank you for your reply, not sure the ph as I never check using ph perfect advance nutrients. I’ve used last two grows without issue. I use cal mag every watering which gets added first no less than 20 mins before adding nutrients which is fully recommended dosage. Only difference in watering was adding the Big Bud last time. Should I be adding more cal mag then?
How much are you putting in exactly?
In the plain water on plain water days?
on days your giving plain water with no ph perfect nutrients I'd like to know the ph.
if it's low it won't pick it up?
Stay safe
Bill
