Is this OK?

It's just a bad gene I had one a couple years ago. Just a weird phenotype. Your next bean from the same batch may be a polyploid with 13 tips , thankfully that is more common.

Under a 300W LED on 18/6. Is an auto from 420Fast Buds in CannaTerra soil. 4 weeks old. Being fed every 3 days. It wasn't a happy sprout and took a while to get to this stage.....so she's no good?

No diary, no info = hard to answer! Start again, this plant was just not meant to be, it happens from time to time. It looks like a clone that was taken when already flowering (??), it wont ever result in much.

I think its just bad luck on this one. Best pull it and start over. Hopefully you have other seeds available. I had a gift seed from Dinafem do this. I grew it out. It was a whopping 5" tall and gave me 1.2g of dried bud. I made it into a drink and it was tasty. It was just luck of draw on autos. I also think I might have shocked it with to much feed. Best of Luck and Happy Growing.

@sativaman she could have and HAD other stresses and that led to that sad end and size ... Nitrogen is so obvious ...

Problem is bad genetic. Nothing valuable will come out of this. (about lower comment: I don't see more than a beginning of N overfeeding. No chance it would cause a plant to behave like this)

Is it an auto flower?

She is overfed with nitrogen and already flowering, I would scrap, you nurse 5-6 weeks more and have 10 grams max, in reality like 3 ;(((( Start again and remember golden rule of grow - Less is MORE !!! All the Best !!!

She looks like it's on flowering phase ? What's your light schedule ? feeding ? how old is the plant ? what light you using ? We need more details
