Ya that will be preflower. I usually keep feeding nitrogen rich fertilizer till bout week 6. 420 fast buds has a great week by week guide for people new to autoflower to check out. Even has pictures.

There’s so many questions here. Where did you get the seeds? It looks like pre-flower so not much you can do at this point. My general advice…use these autos to learn about the plant. Whatever you get, set your goal to be a harvest. Learn how the plant responds to feeding and water. No disrespect to autos, but once you understand the plant photos are no comparison. There are some fire autos out there like night owl if that’s what you want. Depends what your goals are.
