Cheers @Paul Squiggle - glad to hear all is well with you
Welcome to the forum @710Gardenuk, fine looking plants
As BB said, I also feed until I see the first sign of tip burn then lay off a bit with a slightly weaker mix
Your setup is very similar to mine, link in sig
I use Canna line as base nutes/additives and occasionally add off-the-shelf Grow Sure (5-3-8) for extra K/kelp extracts
