Opinions?

as the other growers have said light is way too high thats why your internode spacing is quite large. this is not the best in a plant as you get less budsites. always read your lights instruction book and follow the guidelines in there its usually around 30cm-60cm from the canopy depeding on stage obviously id also look into fan controllers or bigger air extraction and intake fans creating negative pressure is a grow room can be a very good way of keeping everything in optimum values. if its your first grow though well done :) we all make mistakes its called learning and gaining experience. welcome to the community and best of look in all your future grows buddy my dms are always open if you need anymore advice :)

Definitely need the lamp closer or turned up more... or combo of the two. If you did this recently, wait and see before doing more. If that doesn't work, add an hour or 2 to light schedule.

If you want to tighten up inter node spacing then bring your light gradually down so it is about 12 to 15 inches off the top of the plant. Keep temps consistent between day and night also helps. Next time i suggest you grow photo periods in doors. Autos serve no purpose indoors and aren't easier to grow over photo's. They were intended for outdoor environments. They just market auto's to inexperienced growers that think because the word "auto" is in it that it will help them or be easier in some way. You get less yield, and less control with auto's.

The plant looks healthy, good job friend. 👍 My only suggestion would be to lower your light so it is closer to the plant. When the light intensity is not enough you'll see the plant grow very tall and lanky. This isn't necessarily bad, its just you'll see a reduction in yield and quality, especially for the lower budsites. Good luck with the rest of flower.
