I don't quite understand your concern, but I don't quite understand exactly what you are referring to by "organic soil conditioner". If all you did was mix Roots with Happy Frog, then you have nothing to worry about. Maybe let them get established in the new soil for a week or two without nutes, then just kind of read them and see what they want. If you are doing organic, it may be a good time to just consider molasses or some light AACT to build the microbial community, and yes, leave the nutes out for a few. The new soil should have plenty for a while.
Dolomite is typically used as a pH buffer and a micronutrient source, often added for calcium/magnesium supplementation and to temper the acidic nature of the peat used in many soil mixes.
