do i need to flush if i use organic fertilisers?

hey guys i use the hesi organic fertilisers and was wondering if i still need to flush the plants with water, if so why? any advice would be greatly appreciated

some ppl say no you dont have to and some ppl just do it anyway i always flush watever i use just to be on the safe side

thanks for your opinion mate

I usually flush with tap water for the last 2-3 weeks of flowering. That's just me, though.
Plenty of very skilled growers (i.e. Uncle Ben) are proponents of progressive harvesting ...i.e. harvesting buds from the top down not all at once. Let the lower buds grow out after you've harvested the topmost buds. Obviously, you keep feeding until the very last bud is harvested, so no flushing. I'm going to try this on a large snow white I'm about to flower.
