My runoff seems pegged at pH 5.2, I've been flushing with 10ml/gal Canna A+B and 10ml/gal Calimagic at 6.0 as suggested by Jack in another thread, and the plants look a little better, but the pH hasn't changed at all. Perhaps they simply need more flushing, but it's been a little more than a week without change and I'm at a loss, I'm losing money on nutrients, and I can't seem to find any sort of solution on any forum.
I don't really want to start flushing at 7.0+, that'll probably just create new problems, but... I am tempted. :/
Meter's been cleaned, calibrated, and double checked.
They look slightly better than they did, phosphorous deficient though; I've been at this for a little while now, still in veg, and for longer than I'd expected, so I may just start over in pots with real irrigation. :/
This is a coco bed situation, so... I may well be on the right track, it may simply take far, far more flushing than is worth it though.
I've tested it in calibration solution, that should be fine; plus, even if it was reading off, that wouldn't explain the disparity between what goes in and what comes out.
At this point I feel like by the time they are back on point, I could have vegged out some new plants, and the later would cost less, so... yeah, think I'll be going that direction. On the plus side, real irrigation will mean more free time! :D
