Did first flush at end of week. Put about 3 gallons of water into each pot and about 1 gallon came out

During flush I kept pouring in until the water coming out looked clear. Up till that point it went through stages of brown and green

one flower suddenly sprouted white fresh pistils all of the others were turning brown. Was it because they were still too much nitrogen in the soil this week or just a last ditch effort looking for pollen or just a genetic flaw?

Good thing I started flushing because Amber is just starting to appear. I think they should be harvested in a few days maybe?
