gh maxi or flora series,,both great.. plant life 3 part i like 3rd, then gh 3 part, 5th is fox farm or dyna grow..did 3 years testing different nutes back in 2000-2003 all grow great weed once you dial them in to your strains demand.. pick a line and tinker till you get it wright or do an easy 1 part grow n bloom like maxi,or flora dont go over 1 tea spoon per gallon.. personally i use maxi and use grow in veg then i go half grow half bloom for the first 2 weeks of bloom, then go full bloom,,i found going full bloom wright away i got early yellowing,,now i only get the colors in flush..
anyways all work,, additives like bloom boosters not so much,,waste of money imo..pick a line and master it before you say it dont work,,ive tried lots all work just some are alot easier than others,, ive herd good things about canna havnt tried it yet i thought advanced nutrients wer ok but cost is high as u pay for watered down nutes,, in my testing i went for lowest cost nutrients with highest yields,,of course quality of product too. gh maxi is low cost high yield, flora,, bit more expensive but yields are great with an organic tea feel both can be difficult to mix,, or so people say,, i use a paint mixer drill attachment,,never had a problem...good luck and grow well
