I really hate that word flush .... no flush ..... for tea and herc feeds gotta feed on the heavy side so your #s dont drop below that line .. this is what I like about BK , I. won't start till mid veg plant mature enough , then ill hit with a heavy feed if im gonna BK foliar , then I mite do it twice a day but again you gotta be pushing hard on tea days no BK .. SLURRY looks good then feed then back to BK foliar .. if you think feeding now is bad ? do that and see how you gotta keep up with it..... I would only do this if I had 1 or 2 going .. it turns into a full time job with overtime.... you can use BK with a 200 ppm but you gotta know at what strength to use BK 1/8 , 1/4 , 1/2 , 3/4 FULL STRENGTH ....then with a cookie or kush strain you can't get to wild at all . then its either 1/4 strength once a week with foliar ( you gotta test and see ) same with root drench with cookie or kush ..... I never followed any of the feed schedule , the only thing I follow is the order of mixing .... I have a few of my own feed schedule and that can be tweaked ..... indica like this schedule , sativa likes it another way , autos like it a different way .. same thing with using different grow lights and different wattage ... me and wife have really broke it down pretty good...
