Bleaching With Leaves

I have a flowering W/flowers plant that the nugs are looking good about 4 weeks left but the leaves have started turning white, & I mean white??

example:



And no bugs present that I can tell, & they are not spider mites.

I have no clue but when I checked out my plant this morning it had 4 leaves that were drying on the sides and turning white instead of the usual drying leaf look.
someonebetter come up with some answers

Inside or Out? Bleaching is usually due to the shock of being exposed to to much light to fast. Like I had a 1 month old plant that was under a cool white fluoro the whole time, and when I put it outside, the leaves bleached white because they werent used to the powerful sun. Thats why you have to harden plants off before you change their environments from In to Out.
