I use Calmag+ because I start with RO water. Koolbloom is an alternative to Floranova Bloom when you need less nitrogen towards the end of your flowering cycle.

I don't need much for my head honestly, I have friends who need it more than I do. Honestly I've never been that impressed with the flavor of my grows anyways. The quality has always made up for it. I nevr get to cure it for more than a week before it goes out the door!!!!! 6-8 ounces goes quick!!
