Fertilizer suggestions???

Looking for a high nitrogen npk like 2-1-1 / 3-1-1 preferably synthetic and wondered what fertilizers were recomended for cannabis?

I can find plenty of organic ones like planet natural, maxicrop and ageold grow but few synthetic/chemical ones and even less that look suited to indoor cannabis.

Any suggestions?

There is a thread ("reverse engineering everyone's nutrients") in the nutrients forum about making your own hydro nutrients from bulk salts (chemical compounds, or discrete fertilizer products, not sure how to say it) like calcium nitrate.

Usually the high-N fertilizers don't go down to K=1. It's usually 3-1-2 (like MiracleGro All purpose, or Dyna-Gro Foliage Pro). JR. Peters has a Citrus feed that's high N, but also has K.

Amonium sulfate is 21-0-0 and found at any store like Home Depot. (You'd use small amounts. I don't know if it's commonly used with cannabis.).
