You are correct, I harvest by calyxes and trichs, in conjunction with the thirst of the plant. I do not like to chop unless the plant is drooping thirsty, which helps with the consistency of bud when trimming so it's not mushy and difficult to work with (I made that mistake once and never again)!
Foliage pro is the stuff I am using for veg! I love it as well!
I have not tried the chart without the additives, although I imagine they would do quite well without it since Dyna-Gro is such a complete 1 part nute.
Recently I have been using nothing but Rootbastic with every veg feeding except the very last feeding, and I really like the results! It seems to provide all the nutes the plants need (in FFOF soil) with just rootbastic until they are ready for flower. I have noticed faster growth and more robust looking stocks. The most recent round of the Trinity Kush & Qrazy Train were raised this way and given week 4 veg nutes 1 week prior to entering the flower tents.
