Close to harvest leaf curl - is this normal?

Almost time to cut this one down. I'm a new grower and this is my 4th plant. Girl Scout Cookies Auto. In 2x2x4 tent, Vivosun VS1000 LED. Soil, pH 6.0-6.5. I figure I'm about 1 week away from cutting it down. A couple days ago leaves up near the top began to curl and turn brown. Just pHed water for the last 2 weeks. Lite is 75% at 12" (big mistake to purchase 4' tent). Reading GWE says the lower leaves turning yellow at end of grow (right before harvest) is pretty normal. I am hoping this is normal as well with these higher leaves. Should I be worried???

It's generally a sign of heat stress but yes as your plants get closer to the end they are sucking everything out of their leaves leaving them weak and more fragile so they burn easier. It shouldn't be a problem as long as it doesn't get extreme your plants still need a few leaves in order to finish. By the way your plants look good 👍 couple more weeks and they'll be ready
 
Nyce. Thank you for your help. As stated, the big mistake was the 4' tent. Lite is as high as it will go. Grew my first ever plant in my window so the tent was a big deal. Maybe get a taller tent in the future. Thank you again!
 
Your welcome... just keep an eye on it. Another thing to remember is that lights are strongest right in the center so take advantage of this by arranging your plants to where the tallest parts are out on the edge instead of in the middle.... good luck 🌳 😎 and have a great weekend
 
What MeEasy says! You are already close with your light so it is probably a combination of both along with the end of the auto life cycle.
The leaves on my NL auto last grow went from mostly green to all yellow in like 2 days at the end so its pretty normal for autos.
If you can't raise the light or lower the intensity you'll have to ride it out and hope for the best.

Do you have separate veg/bloom switches? You could turn off veg switch, maybe?
 
Awesome. I guess I knew that but really didn't know that. Off to the side it goes (only plant in there now...). Thanks a bunch. You have a great weekend as well!
 
Thank you as well. No switch for veg stage, only power reduction available. Moving to the side of the tent. Next 4 going outside in my Michigan summer. White Widow - hope they get big!!! Happy weekend to you!
 
Droopy, yellowing or burnt leaves on autos - same thing happens to me! I grow outdoors under sun and I've been noticing that when my girls are ready to harvest, they tell me by their leaves turning yellow or brown, curling up, and shrinking. Ph water only for the last 2 weeks of the grow cycle.
 
West Michigan. Lower peninsula. Thank you for your service. I did time as a Marine airwinger. Service got my shit together real fast...!
 
Awesome - thank you as well! Your advice will come in handy when I start the next grow outside (I've never grown outside before...). I'm just beginning to understand when I'm down to 'the last 2 weeks'. With everyone's advice I'll get better (hopefully) with each weed I grow. Thanks!
