Another week of some serious stretching. Some colas are now almost 2 feet above the net. Most of them seem to be about done with their stretch and the buds are forming nicely. I had to do a bit more defoliating this week even though I wanted to wait until around day 44, but it didn't seem to slow them down at all. They are going to need a serious trim very soon. Got a little light burn from me allowing them to grow too close to the light, I should've been on top of things sooner! Some of the most vigorous autos I've grown so far. Very impressed with these genetics.

@Medicrexcellence, Thank you very much for looking and commenting! Best of luck on your grow when you decide to pop these babies, I don't think you'll be disappointed! 🙏 👍
@Legibly1200, Thanks for commenting! The tallest center cola was only 8 inches from the light and was sitting at nearly 1400ppfd with the low corners at 900. I could tell it was definitely light stress as only the colas in the center hotspot were showing symptoms. I raised the light back to 18 inches and reduced the overall par to 800-1200 and they seem to be doing better. Keep in mind I'm running CO2 or these numbers would have completely destroyed my plants. Without CO2 I'd recommend staying between 600-800 ppfd. This is also my first time doing 20/4 hours light schedule which is definitely raising my DLI. When you say you have light burn on tips, that can also be from slightly too much nutrients or even the roots hitting a dry spot in the media. Light burn will encompass the whole leaf edge/margins before completely frying the entire leaf. You might just have some tip burn which isn't usually related to light intensity.
Looking good, saw another dude growing these and it looks like he has the humidity of the Sahara. It
was hard to tell if he had a weed plant or some spinach/raisin hybrid at week 2.
