Espoma Organic Nutes. When is the best time to use?

I bought 3 different bags of Espoma organic Nutes.

1 is dried blood- 12-0-0
1 is triple phosphate 0-46-0
1 is potash 0-0-60

Heres what I plan on doing...tell me if it sounds bad or anyone has a better idea.

At 3 weeks I will add the directed amount of dried blood (1 tsp) to the soil along with tiny tiny amounts of phosphate and potash.

Then in week 6 when I am ready to transplant I will mix all of them in the "new" soil and go into flowering.

I heard plants use the most nitrogen the first 2 weeks of flowering during the stretch phase...or thats when they need it most. So I will add another recomended dose of blood and the recomended doses of the others.

Will the one dose be enough seeing as it is dried granules of nutes?

Any information on espoma or the best way to use dried nute granules PLEASE post!

Im using plant tone from them which has all the guanos and meals mixed together. This would be a good thing to pre-mix into your soil. Then top dress with what you have at specific stages in the grow.

Me? I'm just making some bomb soil with MG organic, humus, manure, alfalfa, peat, perlite, lime, and plant tone. Then im going to inoculate with SPT by Blue mountain organics, ill prbly end up buying their whole line up to feed with that.

Good luck!
