Looking good, welcome to the community.

What’s going on in the top left corner?

Thanks bro, just discovered this community.

Whats happening?

it just looks out of place from the other flowers.

It looks good so far. One thing I would suggest is to use a trellis net to help spread the plants out and keep an even canopy. How big is the grow area? It looks a bit busy in there. With a trellis net, you can use fewer plants to fill the same area. I use 2x4 tents with 2 plants each in 10-gallon pots but I grow with an organic mindset. I use as many as 2-3 nets per tent, the first is to fill the tent, and the others help keep everything even.
