Modified Lucas formula more or less, liquid Koolbloom and doubled down on silicone hence the "fake plant" type of leaves. I used to use 1 tbsp/5gal of silica blast but I doubled that. Never cut out the micro either only so that I have one mix for a perpetual grow. It's probably a bit out dated and expensive but I've good luck with it so although I do mess around with other mixes the Lucas mix with liquid koolbloom is my go to and Dyna Grow for veg with the same heavy silicone dose.
Thanks for that. I feel ya on only wanting to have a single mix because of having a perpetual garden. I went to using Jack's Classic Bloom Booster 10-30-20, from veg all the way thru flower.
