Hey tryguy. I'm an organic grower myself growing my plants in my own supersoil mix, but that oftentimes is depleted 3/4 of the way into flowering, and I finish the rest of the cycle up with the General Organics bloom nutrient. I use it up to the day of harvest along with some sucanat and my buds are always fat, covered in trics, but best of all smell and taste great. Thats what I love about organics, no flush is needed and I can keep given em nutes to grow until chop time comes.
