*Making* my own "synthetic, granular fertilizer" from chemicals via Amazon/etc?

I'm sick of my approach to this, IE "just keep getting different-brands each bag, surely they'll average-out to something 'ok'", I use these granular fertilizers in-conjunction-with instant-release ferts (I consider them as my 'always-there' fertilizer as I water pretty heavily)

I was buying some L.Sulfur on ebay when the Suggested Products window caught my eyes, after a minute of clicking around I'd found:
- 5lbs Ammonium Sulfate $25 (my assumption/recollection being that *this* is the nitro we want for quasi-hydroponic setups IE something that's water-soluble/always-available for uptake)
- 4lbs "Triple Superphosphate", a term I used to think was a brand but apparently triple-superphos is actually a pretty good phos-source, unless my quick googling gave a false-impression it seems this Triple-Super is a staple for farmer-use for phosphates
- did not glance for Potassiums just yet :p

So....anyone ever do this? Furthermore, are those the forms of N&P that I'd want? What would my K/Potassium 'Best Format/Formulation' product be called?

My last bag of store-bought burned some of my trees pretty damn badly, I've been under-impression that it was due to a high Chlorine-content (bag said "No-more-than 10% Chlorine" which, well, doesn't really sound like something you should be giving to organic life, I missed it and suspect I chlorinated my trees with it :O ) Plus, the prices are beautiful.....plus, you can just mix-up the precise ratios you want, changing your NPK%'s on-the-fly, I can't believe I didn't go-for this approach sooner but better late than never!!!


[PS-- as a tangential, anyone ever actually try the "Whole foods, ground-up, as fertilizer"? I've seen some videos about cucumber-skin, banana peel skin, etc being taken and pulverized and used as fertilizer cakes/top-dressings, can link videos if this just sounds crazy to you guys lol but, in principle, the idea did seem to add-up I mean it's "hot composting" right on your substrate-surface but, for people like me who've got bonsai-in-development with the correspondingly-large containers & substrate-surfaces, it actually seems it could be done right....but the synthetics just seem so much better/more-precise, am not worried my soil's "sterile" in fact I re-use soils whenever making new containers so I know that "life/myco/worms" are all coming-over to any new box's substrate, I haven't planted a tree into sterile media in a looong time :) ]

Ammonium sulfate is not good for hydro ....maybe in seedling stage as it does some important things to first roots...other than that nitrate nitrogen is the way to go......some calmag too

Potassium sulfate is good...sulfate anything is good as it increases brix.......also a smaller percentage of the nitrogen can be sulfate ammonium too

Can go Amazon route........can get high quality in bulk from this company Kalix.I use alot of bio stimulants with relatively low amounts of salts.
I learned some interesting thing about bio stimulants like humic and fulvic acids,amino acids,kelp and also how to increase calcium uptake by leaps and bounds!
I spent $1200 and have enough fertilizer for 6 years at least.....I use about 4-8 gallons a day with my business.
Fulvic acid can actually decrease your salt usage by about 20%!!!
I have recipes if ever interested.

To be honest, I think it is only for very few to improve upon commercial mixtures. I doubt you will make something better in general. Similarly.. Making the perfect ratio migh be species dependent and time for year dependent. I doubt it is worth it, for most.
