their actually not bleaching at all. when i look at closer pics you can still see the green, its just buried under trichomes. the tips are not new to me. i have had them in 3 grows with leds. a nug of the white tip vaporizes for 12-15 bags, versus 6-8 with the rest of the plant. so yeah, doubly potent than the rest of the plant. i will do my best to get some scoped pics after harvest.
