Who uses high P and K in bloom with success?

I wasn't planning to update as such but I have to say, this is all going great. They've drank 10 litres of that so far and are putting on weight, visibly and no signs of any problems apart from the GG#4...i thought she was hungry because I saw a 2 or three slight deficiencies but it was K toxicity that was locking them out. She fine really, buds are nice. She's on low K now but the rest are more than happy on the Canna schedule with the 0-9-18 PK. Only another couple of days and ill start dealing back the nutrients on them all anyway. I feel happy I'm maxing it though. Even the GG#4 isn't a problem. I just give here less next time but 9 other clones/strains are fine.

Can you tell me the percentage of Calcium that are in the base nute's and if there is any in any of the additives you use? From what I understand Ca should be roughly less than Half of the K so if your K is 500ppm you'd want your Ca to be 250ppm.

Its Aqua Flores. Ca 1.7 percent, CaO 2.4.

With 4ml per liter of a+b you're at 164ppm of Ca. So when using the PK booster you're ratio of K:Ca is roughly 3.5:1. Maybe it doesn't cause any issues because it's only used for a week like that? Your source water could be adding Ca as well of course..
