The Bushmaster should be run in one of two ways -
1) Added to a res and swapped out after three days or
2) Applied as a foliar once, w/ re-dose in inneffective 3-5 days later.
The Spray-n-Grow is recc'd by manufacturer for use once weekly - 2x weekly only for plants showing a severe deficiency.
The only Humboldt's product that you apply regularley thru flowering is their Stacker/Purplemaxx ( same product re-labeled). With any of their products, it's important not too stress the plants for 48-72 hours post-application. They'll tend to make the plants very sensitive to heat, drought, over-fert, overwatering, etc. I'd never hit a less than healthy plant w/ a Humboldt's product- likely to kill em.
Flush hard before you harvest.
