I did a test grow with H3ads version of the lucas formula for coco. I had to cull them after 10 weeks because they were getting in the way of their elder sisters, so haven't flowered with that mix yet. Up till then, no problems whatsoever and they were blemish free. Will defo use again with coco.
I read the instructions for Canna Coco AB and it's similar to the lucas formula in that it's the same mix for veg and flower and, according to the blurb, full strength from the start. Which is 4ml A and 4ml B per litre. I went through the prices and surprisingly, full strength Canna Coco costs less than H3ads coco mix . £2.36 vs £2.72 per 100 litres. (Regular lucas formula comes in at £4.32 per 100 litres.)
Ionic Hydro or Coco works great in coco,I can't get that stuff in Canada so tried the GH Micro,Grow,Bloom and have been getting outstanding results.

General Hydroponics Flora Series is great stuff. The Grow, Micro and Bloom ratios can be user defined to give (almost?) any npk you want plus the correct quantities of other minerals like Mg etc.
As I use the lucas formula, I only need to buy Micro and Bloom. For coco, that's 6ml Micro and 9ml Bloom per US gallon, which is near enough 4 litres.
