Questions about topping..

So these plants were planted at the same time but I didn’t have soil or nutrients for a while so the 3 that are grown were transplanted but this smaller one is just starting to grow cause I was able to get it out of the solo cup until like 2 weeks atleast after the others and it got really bad looking and took a long time after I finally did transplant it to come back to health and about two weeks ago I got some nutrients for them finally and now it’s really starting to take off but it started flowering when it was barely grown at all so I’m wondering should I top it cause from the looks of it the main cola isn’t gonna be anything compared to how the rest are just looking for some advice this is my first grow ever with auto flowers..!!
