Do you run just a+b and no additives throughout the grow without any problems?
I find if I mix a stronger ratio of just a+b (600ppm) it holds the ph perfectly at 6.1-6.2 without any ph down at all. But my plants are only 2 weeks old any more than 300ppm and they dont like it, so at that ratio the ph doesnt really change from 7.2 so I have to ad ph down then fight to keep it down. I'm hoping the phosphoric acid and less aeration will solve my problem.

One thing I really liked about Canna AB was how I didn't have to ph once the plants were getting fed full strength. I always had to ph up during veg for some reason. Everyone else has said they had to ph down, and now that I use Jack's it's down.

Jacks isn't worth even using unless you irrigate multiple times a day. If you actively monitor your rootzone you'll see the PH is all over the place with that stuff. If the plants could talk they'd probably scream. You get what you pay for.
