Your grow space's humidity is also something to consider, above 60% you do not want to be soaking them with huge amounts of water.
Hypothetically speaking, IF i were 14 days from harvest and wanted to start flushing my girls in soil containers, HOW OFTEN to flush and HOW MUCH to flush with?
Thank ya'll
IF you're growing using organic soil food web methods, you don't. Just give 'em water, or maybe water + a little sugar of some sort, such as our ubiquitous molasses. Doing this at the end of flowering should cause a small population explosion of bacteria, which will fix N into their bodies and give you that nice, yellowed autumnal appearance. Let them get cold during the nights and they should build anthocyanins as well (purple).
Am I doing harm harm im watering with nutes then on the third watering I flush them out
