Iv'e read into this quite a bit.. Trying to find actually science like information not just an opinion.. And I couldn't find anything that says this is actually a really bad thing... On the contrary some of the information I was reading indicated it may indeed be a good sign as according to articles the tested colas with bleached parts had an increase in Thc productions. This is more akin to my train of thought as I am having far more success with light then any other thing. So it's kind of up to you... I myself might avoid it or I might just let it happen depending on how many colas and such.. But one cola is definitely worth trying it on. Just my two cents.. Great work by the way and Jack Herer is a wonderful strain.
