Have read this whole thread, twice.
Once a few years ago, and recommended this method to a friend growing outdoors, he had great success.
Have sort of always tried to follow the lucas formula in one way or another through my years of hydro, FNB, 8/16, sometimes just as a base, with some other GH boosters, sometimes just strict lucas.
Currently i have a new garden ( check my gallery or my thread) running KISS maxibloom. I go into more detail there, but figured i would share some pics of my plants, and hopefully remember to come back and update with bud shots as they develop.
Remember folks KISS maxibloom is 7g/gal of water. I use about 1/2 tsp/gal of protek mixed in first, then just dump the weighed out amount of dry maxi into my res. no hot water shaking, this is 20-40gal at a time, it mixes fine. Works out to about 1.7ec for me.
Since im running OG Kush, im trying to get the most out of her, and shes a mag hungry beast, so i give a little bit extra epsom salts, and 2-3ml/gal of liquid kool bloom in flower at the moment which works out to 2.0-2.1 ec for me. Good clean hetch hetchy tap water.

Thanks for all the help in this thread... Remember keep it simple stoner, this feed technique is supposed to take the guess work out of nutes, give you a very well rounded, cost effective base to start out with if you want to run it strict, or tinker a bit, and really take the question of nutes out of the equation while you play with other more important elements in the room, such as light height/intensity, grow room temp/humidity/vpd, and c02 levels.
Plants... newest shots are 14-15 days of flower.
This is about the point i started feeding full strength, and most mag def signs went away, plants got healthier and happier. Dont be afraid to hit 7g/gal once plants are rooted, they will eat it up!
day 1 flower
day 8 flower
will update later when i have some more mature buds to show off!
