Gonna put you in so much control you can't beat bluelab I've got the combi meter and I had the ec stick before getting that also autoflower always try to go less feed rather than moreDay 11. Had some leaf burn. The Bluelab gear finally came today and I found out I have been watering with over 1 EC. CAL-MAG came today as well.
I reduced Grow A and B back to .5ml/l. That brought me to 0.6 EC. Then mixed in CAL-MAG. Brought me up to 1.3 EC. I guess I used too much CAL-MAG.
Tomorrow will be Grow A and B and CAL-MAG with a max EC of 0.8
My PH meter is hydrating as the instructions said. I will clean and calibrate in the morning.

@St. TomGonna put you in so much control you can't beat bluelab I've got the combi meter and I had the ec stick before getting that also autoflower always try to go less feed rather than more
For plants your age me personality I would be ramping me ec up slightly to no higher than 1.0 maybe 0.9 see how they respond also I would go with your feed schedule and run it at say half measure or if its canna just light feeding@St. Tom
Should I be using CAL-MAG every watering? It's raising my EC a lot. What is your EC for veg? I can keep my EC around 0.6 at .5ml/l of A and B.
that ph may drift quite a while in an hour or check it later this evening but from when i make my food i leave it to sit for the hour before i ph , maybe just out of habit also i generally make say about 6 litres at a time at your age so I'm not making it daily and growbro ya going to smash it just check your ph hasn't risen or dropped each time before you feedTap water EC is 0.1
Tap water PH is 8.0
After 1 ml/l of Grow A, 1ml/l Grow B, 1 ml/l Cal-mag
Final value is EC 1.1 and ph 6.5
So I disagree with the PH perfect claim. I used their recommended dosage and it was 6.5 and not 5.8 with a calibrated bluelab PH and EC pen.
I think because PH perfect nutrients have chelation and will work over a larger range of PH, that is why it works at varying PH levels. I will water with 1.1 EC and if the leaf burn continues I will lower it.
