I've been running it for a while now. I like the stuff.
It has plenty of nitrogen to break down over a good long vegetative cycle. I found that during the first week of flowering I needed to be running a bit more phosphorus and potassium in my system than
Canna coco was offering. Adding more
Cal-Mag Plus to that, and nitric acid pH down, plus the
Roots Organics was just too much overall nitrogen earlier on. This delayed flower onset and of all the things I know to improve upon for next time it is to drop my nitrogen ppm's earlier in flowering. It will get the extra that it needs from the media.
With this media I will only feed at full strength every other time. I alternate with 1/2 strength, balanced (1-1-1 1%Ca 0.5%Mg), solution with good runoff to ensure the nutrient buffer is not washed out but all the extra salts do.
Working with the EC I found my strains worked best on a veg solution starting around 0.8ec and working up to 1.2 ec. You could probably push them up to 1.5 without too much issue. During flowering earlier on I start lower, around 1.0 and gradually work up by about 0.2 every week until hitting around 1.8ec, then to hang out around there for a while.
Keep the Mg levels high when you have a higher EC. I add about 0.05ec of Epsom Salt every feeding for that extra few ppm of Mg. Also, decrease the Calcium progressively the further you get into flowering. I found that the plants really just needed a good amount of PK because they were pulling in so much N from the mix.
A nutrient I used later on that worked VERY well for me, at a reasonable price, is CNS 17 Ripe. At 1-5-4 it gave me the right ratio given the properties of the media.
Good luck.
