Long Time Smoker, First time Grower.... Question about DTE and living soil

Hey everyone,
If this is in the wrong place, forgive me. I'm a long time smoker, soon to be first time grower. I'm going to be running 4 5gal fabric pots in a 3x3 with a 240w led. I chose to go the living soil route and ordered Down to Earth 3-3-3, Rose and Flower mix, and Acid Mix. Plan to use Roots organic original soil and worm castings, with weekly spraying of coconut water.
Any comments of my choices? DTE state 1 to 2 Tbsp per gallon of media, so 40 Tbsp. Plan would be to mix 20 Tbsp of 3-3-3, and 10 each of the Rose & Flower/ Acid mixes.

Sounds about right. I feel like 1 cup (16 Tbs) of amendments to 5 gallons of soil is pretty standard, especially if you're amending soil that already has some nutrition in it. So you may have to top-dress before and/or during flower if you're using the rate you mention.

Thanks for the response. My plan is to top dress every 4 weeks, or when needed. Is that enough, or should it be more frequent?

Personally I'm not an expert on top-dressing, but every 3-4 weeks also seems pretty standard. If I were you I'd keep something fast-acting, like a liquid fish type thing, on hand in case you notice deficiencies. Dry top dressings will take a few weeks to kick in, so by the time you notice things falling off it's gonna be too late to use them as a quick fix.

Ime, living soil works much better without the fabric pots. Thet tend to dry out a lot in the perimeter, which isn’t a good thing for living soil.

edit: unless you use this type:
