Small Buds - no swelling

I am growing an autoflower. The plant has been in flowering for several weeks. The buds are not getting larger. They are not swelling. I am using coco coir and a Bigg1000 led grow light. The plant has done fine except for the size of the buds. The trichomes are still clear. I estimate the plant will be ready for harvest in about three weeks. I am attaching photos of some of the buds. This is my first grow. To me, the buds do not look normal. I am familiar with the term popcorn buds. Are my buds popcorn buds, and if so will they ever be anything else? Am I wrong about how close to harvest I am? Is there anything I can do at this late stage to increase the size of the buds? Or, should I cut my losses and harvest when the plant is ready?
Thanks for your help.

If it weren't an auto, I would have said the plant looks like it's in reveg.

It looks like a nitrogen tox to me. Cut back on feed that has nitrogen in it. To much nitrogen cause the dark shiney leaves, and small buds. It may come around if you just go straight water for a while.

You overfed and stunted the plant. There's nothing you can do now except finish it out and get what you get.

You said you were running a bigg1000. I don't think it's putting out the light you think it is because your plant has an awful lot of 3 blade leaves up and down the plant.

Also appears to be a toxic over feed and I do not think she will do anything worth a F. I'd cut the thing down and start another. Wouldn't even try finishing it. Straight to the compost heap.

How many watts does this light actually use? It’s not 1000 watts.

That's what I thought too, but I know nothing about auto's

Looks like nitrogen toxicity as others have said. You might try flushing and then adjusting your nutes for the home stretch and for your next round.

You're joking.

Your advice posts are so wrong that it is downright offensive to people that actually grow plants, they should get reported to admin for banning.

Definitely classic nitro toxic. My first auto was a GG #4 and towards the end of the cycle I ran out of the flower base (2:2:4:2) and used a 9:1:6 for the last three weeks.

new growth looked like reveg and it started popping fresh foxtails all over the place.

Your plant is fucked buddy. Waaaaaay to much nitrogen.

Too much nitrogen will retard flowering. Which is exactly what you have demonstrated here.

Live learn and cut your losses and start again.
It hurts the first time- but like any farmer- you will get used to killing something you cared for. Don’t waste any more time on these.

Thanks to everyone for your input.

I flushed. I am going to stop the nutrients and water with PHed water and see what happens. I am probably wasting my time but maybe it will continue to be a learning experience.
