Yes

8/16 soil and 6/9 coco of micro/bloom. No number for grow cause its not used in the formula.

I used it for soil for many moons with great success. I have moved away from it but it can put out some dank.

I've switched after 15+ years of running modified Lucas.

I don't know if it has to do with Scott's(Bayer) purchasing the company, but my results have definitely gone down in the last couple years. I loved Lucas - mostly because I do frequent week long surf trips and the PH stayed rock solid the whole time, but diminishing results have left me baffled.

I switched lines to V+B HD and am back to crushing it. PH upswings for the first day or two are a bitch, but it levels out.
