First grow

Looking well. I’m growing this as well so hopefully I’ll get some tips from following yours.

Hi mate yep she can be topped Please see my answer to ya question above for more details 😀

Autos have a very small window of opportunity for TOPing, it has to be done above the 4th node, removing the 5th pair of leaves, before they fully open, by the picture it is hard to tell, but it looks like it's past that point and it's on the beginning stages of flowering. I would not top it at this point.
