Green Fire - Rainbow Pie

@kaneownz, This is my first time using Jacks formula myself. Previously I had been using Canna Coco nutrients up until this point. I am using also using the 321 formula. more precisely: 3.6g - Jacks A | 2.4g - Calcium Nitrate | 1.2g magnesium Sulfate Along with some some beneficials: Silica, Kelp, Recharge, and Tribus. So far so good! In second week of veg ran into a little bit of a calcium or magnesium deficiency, (probably because I am growing in coco) so I upped my cal mag a touch. Since then everything is looking happy and healthy. I believe Happy Frog soil mix may already come with some nutrients enriched in the soil, so I would be careful not to over-fertilize by using Jacks at full strength. Soil growing is a little bit dif. then growing hydroponically in an inert media. You want to be careful to only feed as needed, at a lower strength or once the plants shows you it has depleted the nutrients provided by the soil. Good luck!
