so i read where you were having bud density issues with jack's and now i know why.
jrpeters shows 2 ways to mix.
one is the "small batch" method wherein they recommend equal parts. i have used it for years because it was fast and easy to do and it works quite well in general.
i assumed it was the same as mixing by weight but i actually weighed it out and found that the equal parts results in significantly more calcinit and therefore more nitrogen.
i changed the reservoirs around so that i'm running the 1/.66 ratio by weight on the flowering, stretching, and large vegetative plants in frames and the bud density improved dramatically.
i still use "equal parts" on all clones and small vegetative plants as it gets me more growth during that period.
Freakin great info, thanks
