Correct, you can flush until the trichomes are ready to harvest.

I know of many who have flushed for 2 weeks, just be prepared for the fan leaf and other larger leafs to yellow and die off. You can pick them off once they are yellow they server no point for the plant and only block air flow and light.
Zandor Reviewed by Zandor on . flushing when flushing does it matter if you go over five days. and if you get to the 5th day and it will be another day or 2. should you use just plain ph water. Rating: 5
