Ty man! I have La Diva, SAD Auto, Dutch Passion Blueberry, g13 Labs Pineapple Express, Pakistan Ryder, Purple Jem. I have a pocket microscope from Radioshack. Theres only a FEW new white hairs from new bud growth, all around the plant but the mass majority of the hairs are a DEEP RED almost brown. I may try the 24-48 hr darkness thing. I read mixed reviews regarding it.
