I am a bit confused. You are flushing right now? If so, used PHed water, with a cleaning product in it...no nutrients. Make sure the water is PHed. If you have already done your flush, continue with your flowering nutes, however you should be careful to not hit them with full strength immediately after the flushing. I do 3/4 strength and it worked fine, I know some people do it slower though. Best of luck
