Hey there dizzy,welcome aboard! GWE has great
guides on how and when you can top your plants depending if they are photoperiod or autoflowering .
Depending on what you want to do (
manifold,
mainline,
fluxing,
LST or
ScrOG)the main/top cola should be topped differently and in different times/places or even more than once or twice. I said earlier in another post,topping requires foresight,at least to know what technique you are going to use so you can time it all.
I understand this is your first rodeo so please,don't let my post overwhelm you with information but let it give you frisky ideas about how to treat your girl/s in the best ways so they can return the favor
Enjoy the most addictive part of cannabis dizzy,Growing it!
Keep it Green
PS
If you are ok with it it would be very nice to see your setup and girls (pre-cut or post-cut) so we can have an idea of what you are doing,if not to help you,to learn from you
