I've recently read that you should flush your organic crops 2 weeks before harvest, but this can decrease yeild.
One thing that confuses me is that i've read that organic (soil/ compost) crops should be flushed every 2 weeks. Can anyone shed any light on this? I appreciate most people probabaly grow hydroponically, but if anyone does grow organically, how often do you flush the compost? At the minute i'm doing every 2 weeks, as recommended by Mel Frank in his book European Cannabis Cultivation (an old book now though, lol.)
