Might want to cut that soil with an equal parts of perlite, vermiculite, and peat moss with a little lime and Cal-Mag. And then remove the part of MG from the bucket.
If you can't remove the MG, at least you will have thinned it (and the stuff in it) down to 25% and lightened your soil.
And you can water to the point of runoff, say two or three times the volume of your planters to wash out some of the ferts each time. But I don't know how well this works with the time-release stuff.
