m0useanswered grow question 3 years ago If your light cycle has not changed, and their is no light leaks. Chances of it revegging are next to zero from my experience.
A revegging plant will put out weird growth from the buds like a smooth single blade leaf and start to grow stems.
Looks to me like its still growing as per normal.
The strain is said to be 55-65 days. or 7.8-9.2 weeks in flower
Your diary is on week 6, so just a bit more to go till the "estimated" harvest date, can go beyond that time frame.
Good Luck!
