Sugar Cane & Dirty Kush Breath

White pistils continue flushing out at the beginning of week 6 with the Sugar Cane. One of them is getting more purple than the other but nowhere near as purple as ol' Dirty Kush Breath! Really unbelievable and mesmerizing trichomes on the Sugar Cane! Top shelf looking smoke on both of these strains! 6/2 was the start of week 6 for these. I added a teaspoon of kelp meal and a tablespoon of fermented banana juice per gallon on the 2nd. Being my first completely organic grow in super soil, and only 3rd successful grow ( 2 previous w/ autopots were a failure and resulted in going back to soil) I'm curious about when to or a need to flush. In my research, I've found some saying that flushing isn't really needed if grown organicly in soil or only only a few days before harvest instead of a week or two of flush. Is this correct? These are the best looking buds I've grown to date and would hate to eff up the finish on them. Any advice from organic growers? Its now less than two weeks to week 8, trichomes are still mostly clear on all plants.
