I have used bud blood and then follow that with big bud. Also have used liquid Karma. Both made a good difference. I got some Gravity flower hardener just a couple days ago to fatten and make your buds hard. I don't think my bro will use it, he just don't like to try new things. Once he see's me use it he will beg for it if it works. Same company makes Bush Master. It may help you. Bush Master is for veg time and it makes the plant stop going up and bushes out. I hope to use them soon. Check out the bushmaster and we will compare. I might get to it first.

Oh and as for nutes. They are all formulated for one thing only and that's what we do. So more money doesn't alway give you more in that way. Yes some maybe alittle better because of like you say PH buffer but most do that too.

Do a search for LOC NAR and go back a couple years. I got my first grow log on here. It's funny tooo, check it out. The grow logs they busted me with some good friends here deleted just in case but I have all the pic's if you want to see some.
