Those plants don't need to be outside if they can be right inside a southerly facing window (pointing anywhere from SW to SE).
The MG products are almost always dosed way more than your plants need or will be able to use indoors. Just out of curiosity, what's the volume coming out of the pump, approximately (using a measuring spoon to get a rough estimate)? For reference, I use the regular MG granulated formula but I use it at 1/20 the recommended dose (that is 5% of what they say to use) for my outdoor plants.
