What's up. Normally I don't suggest people stop using chemical fertz because it sounds pretentious (no offense Kremmon), but I have to say I agree that Organics is simply the best for use on marijuana. Now I kinda feel impartial because I use a bit of MG 20-20-20 in my brief veging period but once it come to flowering it's all organic baby. One reason is I don't want to fuk-up my plant by overfertilizing it (not using it properly in other words), but it's easier to over-fertilize with chemical, so that kinda sucks. The Main reason is that by exposing yourself to some of these chemicals, you are potentially exposing future offsrping to mutations, and complications, trust me it's not pretty. If we're talking dollars it's not that much more expensive.
Also you mentioned your pot has never tasted funny, you wont taste chemicals altering your DNA. And dont tell Kremmon not to come onto your blog and "disrespect you". If you can't handle people giving you good advice, don't bother with Rollitup. You hear people say all different numbers of days for how long you should flush. Some people say 12 days, some say 14, on this very blog somebody said they flush for like 2 or 3 weeks. Most likely the truth is nobody knows for sure how long you need to flush before all trace chemicals are gone, or if they are ever all gone. Sure you can flush for like 4 weeks to be sure but where's all the nutrients your plant needs in that time. Chem-fertz are going the way of the dinosaur as far as marijuana is concerned, wait and see, or be a part of it.
Using organics is some of the best growing advice I got when I first joined this site, I would heed the advice all you MG representatives. (at least for flowering). Peace bras
