Shoot the Bio365 guys an email about their soils. They might recommend you a different one. I think I would go with BioFlower. I'm pretty sure they recommend it as a water only with minimal feeding, maybe once in flower. I bet you could get away with just water and a couple things like humic/fulvic, kelp, mykos, molasses.
From an email I sent them:
BIOALL has enough nutrient to get through a veg cycle without feeding. Then starting in flowering, you'd feed as directed by your flowering fertilizer of choice. In reality, the biological and chemical buffers in BIOALL probably allows you to cut your flowering feeding back to about 80% of recommended but you can keep it at 100% if you prefer.
If you want to grow all the way through in one soil with minimum of supplemental feeding, BIOBLOOM or BIOFLOWER are the way to go. BIOFLOWER is a little more forgiving / has a wider sweet spot but BLOOM has just a little bit more air-filled porosity and so, when you get it totally dialed, allows you to push the plant just a little bit more than BIOFLOWER.
With both of them, it's possible to grow water only all the way through but the plant won't be maxxed. Again, if you want to push the plant, you'd feed at 1/4 strength of fertilizer recommendation throughout the cycle.
EDIT: They aren't carried anywhere near me so i'd have to order online. NEhydro carries their stuff.

EDIT2: Soil is about $20 and it looks like shipping is $20-25 for a single bag. $50 for a bag? Not terrible since I paid the same for BioBizz LightMix off Amazon. However, you may want to find something similar available near you or try buildasoil
@Proph recommends their stuff heartily. Might cost the same or less for a definitive "water only" organic living soil.
