No doubt they will show sex with 6500k's. I know people who use them throughout flowering, not reccomended but whatever.
Well, with sativa strains especially, some people wait to switch spectrums after they switch light schedules to deal with the stretch. But switching your spectrum will make it happen quicker yes.
Man if you are doing it outdoors and just want to know the sex of your plants and keep vegging, the cfl's that you currently have WILL work, might take bit longer if they are in the blue spectrum but will ultimately do the trick.
Exactly, guy is growing outdoors just wants to see sex of plants, no need to buy more lights Just trying to help out.
