GH 3 part in coco?

Many people have used the "Lucas Formula" of mixing the GH series, in conjunction with coco, with great results.

You basically ditch the FLORA GRO, and use only FLORA BLOOM and FLORA GROW throughout veg and flower...

Coco has a tendency to 'steal' magnesium and calcium from your nutrient solution, making it less readily available for the roots to uptake. You can circumvent this by soaking the coco in some CalMag+ for a day before beginning the grow, or by adding a small amount of CalMag+ at each reservoir change.

should work out well but use cal mag when using coco lucas formula is way to go with GH if you can handle it

GH's newer duo part A and part B are nothing more than premade Lucas formula.
