help with moab (mother of all bloom)

I am currently using advanced nutrients 3 part grow micro bloom and just got some moab because im going into flower in the next few days. Anyways should I reduce my 3 part base nutrients by 50% or all together? I know the 3 part is fairly low in all 3 nutrient numbers and moab is considerably high. I know im going to start moab at 1/4 or 1/2 strength either way but any help would be appreciated.

Oh and after I use it for the first week or so I should just go back to the original full strength base nutrients? ? Just trying to get the proper method for moab use, thanks all
