Don't think so, i use biobizz and researched the ingredients first, contains all 16 micro and macro and is mainly molasses and beet, cheap cheerful and dose the job, hence why i went for it. Most problems with ferts are the soil and water quality not the actual ferts themselves. I went with a dutch grow company for ferts because they grow good sh!t in holland, the best sh!t in fact
Tomatos have specific ferts but i don't think they grow great toms, this is down to the grower and strain. Maybe you should try some of the more specific dutch ferts for marijuana because over here we don't know dya-grow or fox-farms but in holland they have stuff that will blow you away and they are real serious about growing weed, don't know if you ever been to amsterdam but if you did you would realise that this city is built on weed and they would disagree with you.
I went for bio-bizz because it was aimed at most plants and wasn't trying to be specific as well as the fact that they are a well established company that know there ferts and have years and years of getting it right. I find hydro is more specific for weed.
I think the dutch have a different attitude to ferts and growing weed than the american market, you guys seemed trapped in the hype wheras we just have a lot of good ferts and products that grow great weed, marketing is not so important here so much as reputation amongst fellow growers.
Why would you diss 'Canna', i think you are wrong here, some of the best ferts i have seen and they aren't just aimed at the marijuana market, call the company or ask for an ingredient list, think you will be suprised at how good they are on paper! Most people over here prefer the canna hydro nutes for soil as they seem more complete than the canna soil nutes! Seriously, you got some kind of problem with canna because if you have i don't think you are using ferts the right way.
One part nutes suck for marijuana, nute requirements change with veg and flowering whereas my peppers prefer a one part fert as their veg and flowering requirements are the same throughout. I really think you should read what you have written because you seem trapped by the hype more than us! Up to you which ferts you use!
