yield from using water only fox farm ocean forest?

I want to do a straight water only grow, I was planning on using compost I found online but when I looked at the shipping costs it was like 75 bucks... soo yeah fuck that. Decided to go with fox farm ocean forest. Just wondering what kinds of yields people have gotten using water only with fox farm ocean forest soil. Im doing a 4x3 scrog in a 7 gallon smart pot

You'll need to add stuff to the soil or eventually need to feed it something

would it be better to look up the water only mixes they have online? I was considering doing that because from what I have seen they have some that include only store bought soil and whatnot. I dont have time to compost for this grow cycle.

You can definitly get away with using fox farm happy frog soil and get there happy frog tomoto granulars and add a few tablespoons every 3 weeks and then you can use water only add dolomite lime to the soil before transplanting if your not using tap water and eliminate calmag issues or use tap water without the lime
You'll be golden if you use lime and tap water you'll not even have to pH the water

You CAN use FFOF alone .... It can carry a plant satisfactorily til WEEK 5/6 .
Which is the time i introduce BLOOM FEEDS.

Depending on container size and strain ( heavy feeders ) - FFOF runs pretty long before signs of nute exhaustion. When the soil is starting to deplete and has been on a water only diet ( tap - because there are soil buffers in it to control ph ) .

I have saved a lot on unnecessary ( grow feeds ) again depending on strain.
All i end up doing is adding additional P and K during flowering to get mass and weight.

Here is an AUTO JACK HERER on a WATER ONLY GROW !
Soil is a 80% FFOF with added perlite ( aeration / drainage ) AND 20% Light Warrior
( great Myco / Humic Acid ) as the upper topsoil.

No burns , just water every couple days or so.
