Whats the best hydroponic nutrients and addatives

i was just wondering what type of nutrients and other addatives thats cheaper and would be good enough to do a good hydro gro

i use gh its cheap and does great

I like Dyna-Gro, it's complete nutrients in one bottle, good quality, and pretty cheap.

foxfarm also has good 1part nutes.
grow big for veg and tiger bloom for flower.

I hear ionic is also good 1part nutrients.
