When to flush

You are still bulking, and have 3 to 6 weeks left would wait as to not lose weight on yield. In soil a 2 week flush is recommended of any water. The point is to get the plant to start using stored energy and start showing deficiency at end as a stressor. So if you soil ph locks out that is fine. You want roots to stop working then anyway. Only way a flush is not needed is if you are not providing decent nutrition. Flushing makes a huge difference and have tested it myself. Bud will have a bitter nasty taste if nutrition is still in the plant. I have done the experiment that noone seems able to find on the net, and yes flushing is required in indoor growing for sure. 2 weeks soil 1 week hydroponic. Providing extra potassium and phosphorus is ideal in flowering for denser, and potency of buds. Very light nitrogen at your stage. Buds will also be dense depending on how many grow points your running. More can make it less dense few will make it more dense for future grows. Good luck mate and enjoy the harvest in about a month 👍 🤜🤛🌱
