Nutrient Tea Recipe NPK feedback

Hey folks, grown with synthetic nutrients for a long time but giving this organic thing a whirl. Would someone be able to constructively critique this tea recipe I worked up? This is for application to some plants that are already growing and topsoil amendment is not feasible at this time.

Recipe is for a 90 Gallon tea brewer with 2 X Ecoplus 7's.

400 Grams Bat Guano (9-3-1)
160 Grams High P Bat Guano (0-13-0)
400 Grams Alfalfa Meal (2.5-1-1)
200 Grams Seaweed Extract Powder (0-0-17)
100 Grams Crab Meal (4-3-1 + 14 Ca)
400 Grams Earth Worm Castings
90 Grams Epsom Salts (9.8 Mg, 12.9 S)

50 Grams N
37.8 Grams Total P X 0.44 = 16.63 Available P
43 Grams Total K X 0.83 = 35.69 Available K
14 Grams Ca
8.82 Grams Mg
11.61 S

Mix will have cal mag added before application to have Ca between 1/1 or 0.8/1 ratio to N and MG at approx 1/3 ratio to Ca. Micronutrients such as zinc and iron should all be covered by the seaweed. The multiple ingredients might sound over complicated but I am trying to cover all the NPK bases as well as applying as many chitin rich products as possible (High N Bat Guano + Crab Meal) which have been shown to create pathogen suppressive soils along with Alfalfa for the triacontanol.

Any thoughts/advice/critique welcome!
