To be honest there is alot more to it than just a magic elixer.
there are lots of other variables to gain control of before you can expect bumper yields.
I personally am still using what i did when i first started. I am using IONIC COCO GROW/BLOOM/BOOST
These 3 nutes are pretty cheap and work pretty damn good. I havent had any deficiencies that were a problem. A little N def in the beginning through not feeding enough.
But your climate is the biggest thing to get right. Get the Environment right and your plants will show you what they can really do.
I cant say which out of all the nutrients are the best because it all depends on who's hands they're in.
