Looking good Jay. I never do anything about deficiencies outdoors, the plants have a much harder life outdoors and they always pull through without adding stuff. There’s always loads of rough looking leaves lower down. Give it a month and they’ll go BOOM!
Fair point mate, and I can see yours look like they had the same thing, yet delivered the goods.
Not going to do anything drastic, just up the seaweed extract a tad and maybe some mollasses, see how they respond, i really suspect K def tbh.
