@Rollk1 Welcome to the forum. Lots of knowledge here and people willing to share it!
As a newbie grower myself, I will add only what I have experienced and learned firsthand. First, I see you have 1/2 gallon pots from P4P, correct? I went the same route. I them had the same stretching as you are now having. I think it is misleading when they say just put in a windowsill. The plant gets deprived of essential UV spectrum light. Then the weak light I started with. All this equaled lots of stretching! I finally got a better light (still not a high quality one) it slowed the stretching but then got too tall for the grow closet. Had to LST the plant as it was less than 10" from the light.
Although they seem to be doing well, the combination of stretching, poor lighting, stressing them out at the beginning of flowering, and being in such a small pot, I have very small buds. However, they look great.
So, light is very important, as mentioned already. You can search the forum for threads discussing light option and recommendations. I think a quality beginner light will run about $250-$300, which I didn’t have to invest at the moment.
If height is not an issue, you can let her keep going. I would bring the light down lower to stop the stretch a bit. You may want to consider LST.
Good luck. Keep posted.
This is an Amnesia Haze. You can see the stretch and how I had to bring her down. This was a week or two into flowering so I was nervous to do it so late.
This is week 6 flowering: small buds - looks great.
