I think the pink is natural... and its related to the light it gets.., on the top bud, as soon as a new pistil comes out it turns pink the following day. The bottom ones ae yellow cause they are so far away from the light...
So yeah there are new pistils coming out everywhere, but the farthest ones from the light arent as pink, and some even yellow.
Hey Mr. Bitti, did your mazar stretch much after flowering I know you other plants did, but not sure about the mazar, cause i get the feeling my mazar at 12 inches is pretty much done stretching.
