My protégé used this stuff for his first grow. It's a never ending battle of having too much of nitrogen throughout flower phase and an uncontrollable pK values during seedling stage. I'd cut it to 1/4 strength and see how it goes. Only feed if it looks required, and allow pits to dry completely. It will be a struggle, but it's doable. If your using the soil below then you won't need to feed for a while. Cont.. Below
Again it's not the ideal media to use but it will work. It's going to be a little "hot"( full of nutes) so I'd suggest doing a major soaking before you plant anything in it. Do a nice big flushing and leach out as much nutrient from the medium as possible, then you'll be much better off than using it straight out of the bag. You could also cut it with more perlite and/or vermiculite or extra peatmoss. If this is all you can find, then it'll have to work. Again it's more work for you with possible issues with nutes, but it's totally doable. The biggest thing I think you need is a good 2 or 3 part nutrient. This way you can control NPK individually, instead of all at once.
