new to outdoors in bc....purple??

Hey everyone!

This year a friend of mine gave me a little girl that he had no room for. I've been told that its Texada Timewarp, and I believe it actually may be considering I can see Texada Island from my front porch. I've been growing her outdoors, and everything seems to be going alright. Shes been flowering for about 4 weeks or so now (im not 100% sure, I didnt want to depend to much on timing, and decided she'll be done when shes done.) and I'm starting to notice the little leaves at the top of the buds are coming in with a slightly purple color. Temps at night have been getting a little low lately, but nothing to alarming. Could this be the cause? Is this normal for this strain? just curious.. heres some pics.

It kinda looks like a light cycle disorder.. For example does ur neighbors have outside lights that shine into ur back yard or any lights in ur own back yard if a plant doesnt have 100% of dark it wont fully develop buds and will grow little leaves in the bud the buds dont look very big for being 4 weeks old either.. It looks like it is reverting back to veg to me idk it could be a nuti problem maybe!!
