QUOTE=Gigawatt;6358701]During what week (of flowering) should you start to see buds form?
[/QUOTE]
Are you talking pistils or formed buds?? Pistils in 1-2 weeks after 12/12, unless they began to show their sex while still in veg, (pre-flower). Those bud sites are, what Cannabisguru stated, nothing more than calyxes and pistils. The pistils emerge 2 at a time from a single calyx, after awhile, the pistils are drawn back into the calyx to see if they have become pollinated, if so, seed growth will begin, if not more pistils are put out, looking for pollen. That's when the buds start to form and grow....
View attachment 1808713 This picture shows the pistils, still very hair like, and white, seaching for pollen
This picture shows the pistils browed/reddened up, withdrawing back into the calyx, where it will be checked for pollen. This stage of the bud gives more of the appearance of what a bud looks like when finished, or being close to finishd.
Hope this helped! Peace.
Both these pictures are off the same plant and taken the same day!!
