I was using a 50/50 blend of HF and FFOF for a few years before I discovered Roots and other blends.
Honestly though with all the work of making a soil and yeah bad back, age, lack of time, I say to Hell with it and just buy it.
Every now and then I'll grab a bag of Happy Frog but I've steered away from using Ocean Forest. OF has sand it in it and seems to hate my water and room but I'm groovy with the peat based Happy Frog.
Are you seeing Fox Farm stuff at the HEB near you? Their prices are actually better than the hydroshop here and they store it inside unlike the other garden center here that keeps it outside with not even a carport style cover or even a tarp to cover it.
But so far I've only seen one HEB stocked up like that with Fox Farm stuff and it's a big new one less than 3 years old.
