Advanced nutrients test their products on real world Marijuana.
BC Hydroponic nutrient 3 part is good too.
I have used General Hydroponics 3 part nutrients for many years with great success.
I do like mixing GH and Advanced nutrients supplements like Bud Blood the first week of flowering. Then switch to Hornby's Big Bud, add a little fulvic Acid, B1, CalMag plus and a little Piranha or Tarantula depending on what strain I am growing and the method of growing.

Is that what you are looking for?

There is easer stuff to use and GH & Advanced both have single application formulas that are easy to use and have been tested with marijuana. I just am a control freak when it comes to my plants.
Zandor Reviewed by Zandor on . Why no MG? This is a question that is largely based on curiosity, i've noticed all the different kinda of nutes and stuff for you plants and even organic nutes like from ali bongos or something but i was just wondering as to why we're not aloud to use MG anyway...most noobs would find it a cheap alternative then to all the branded nutes and then normally get a shlapskie for using MG...why? can anybody shed some light on this?
