First time. Whats wrong???

This is my first attempt. not exactly perfect but its been going ok up until about 3 days ago. Than i started to get this and it seems to be getting worse. Only the top of the plant seems to be affected. 5 weeks into flowering.. bag seeds no idea what they are.

i have no idea, thats the craziest kind of weed ive ever seen! what kind is it?

Many years ago +30 I had a plant like that. It's just the seed. Start over but keep growing that for fun.

So you saying get rid of it and start over? Under that top set of leaves it looks great.

No, not start over, but different plants look different when they get deficiencies and stuff, so its hard to tell what your plant issue is thats all
