Haven't really read much, upto the point where you said your using canna products, may be different as I've heard some companies have different formulas for each continent.
I started growing on Cannas organic line, with bio boost, gave that shit up after the bottles ran out for plant magics old timer line, no boosters (a bottle of mollases is cheaper and practically the same) and had much better results, but then, none have been better than making my own soil & teas now.
In Europe Cannas organic range is thought of as shite by most UK growers, their chemical line is good but its chemicals!
Cannas organic range, veganic if u want to call it, is overpriced bollox.
Ive never gotten vegans personally, or even vegetarians, I know this is medicine, but I bet the majority of the people that smoke/ingest marihuana probably eat meat or animal products in some form, so why restrict from feeding them to ur plants, when for 100s if not 1000s of years theyve been fed to plants (I don't know for fact this, but its logical, horse manure, chicken shit will have some type of animal matter in them and people have fed this for years.
i can understand not wanting products with something gm in them, but in this day and age most things can be sourced, I know you can get blood meal and bone meal, thatis organic and gm free.
honestly I can understand organics, I grow organically, but vegan, come on. Next they'll be people saying, wait , don't cut the plant down, it has feelings too!
