When do pistils really take off?

I have been anxiously waiting for pistils after switching my baby to 12/12. After 18 days they finally appeared on one side of the 2nd node from te top. They are small but visible and have grown a little over these 2 days but nothing crazy..
I check my baby all over and see no new pistils, so my question is when could expect to start seeing more pistils?
The 18 day wait killed me!!

Ps. The plant seemed to have started growing faster after those two pistils appeared??

How long did you veg for? from seed or cuttings?

Vegged for 21 days 18/6 from seed then flipped to 12/12, she suffered some heat stress at like week 1 but recovered extremely well
Edit : she is 40 days old today

Just relax. Strains differ, and some flower faster than others. The plant knows what to do without you finger blasting it every 20 minutes looking for pistils lol (Though I fully understand the urge).
She might be real slow to show and then just burst into flower like a raped ape or she may remain more reserved, but she's got it all planned out already.

ETA: The heat stress could slow it a bit, it takes energy to recover. My flower room had some stress at the beginning of this cycle too. Don't sweat it.
