Question about ferts

I have a couple questions as im preparing for my outdoor grow..
So far im planning on using a regular fertilizerless soil.. so for veg I am planning on using cal/mag (when needed), super thrive, bat guano and alaskan fish fertalizer.
I need help with my bloom fertilizer. I am planning on using molasses, and cal/mag when needed, should I use bat guano's and top amend? or fox farms bloom nutrients? Im not going for the organic side either it doesnt matter.. I think top amending will be the best idea because im not planning on visiting the plants every week.. probably every other. How often do guanos need to be re applied?

It should be raining every week or two that time of year (flowering), just apply granular phosphate and granular potash every 2 weeks till the end and youll get rock hard and full buds. Also apply a high quality slow release veg fert(3-4 months) to top of hole after planting, water with fish,guano whatever every 2 weeks.
