When/if should I TOP/FIM this clone??

Hey all, first time grower here!
I have a 2x2x4 tent setup, with only 1 clone growing right now that I just transplanted in a 5 gal smart pot (3 or so weeks since getting back from the shop) I know it’s a big pot but I’ve seen some say it’s okay as long as I can get her past the shock.) using a 130w (300w equivalent) LED, and running roots organics original not the 707, with some MG perlite mixed in (not my first choice but all the store had). I know the perlite apparently has some ferts in there so I’m definitely not feeding still, especially cuz I heard the roots it’s really hot. Gonna be feeding fox farm big bloom trio when I do. ANYWAY, I’m not sure what to do about topping or FIMing this baby right now! I know I might have let it get a little big before topping but I couldn’t find a good time with even nodes to do it! So my question is what should I do with these uneven nodes growing on my plant? When should I top? Or SHOULD I top? Should I FIM? Need a little help if possible! Shit, I will gladly even accept the hate comments if it’ll help me get a nice first yield! thanks guys And happy smoking! P.s. the first image is from transplanting to 5gal 3 days ago

Mekilu I like to top above the third node, gives a node below for safety in case something messes up with the first top. As well the second set of branches should catch up and you'll have 4 colas.

Your plant is a clone so sexually mature and giving you alternating nodes. It makes topping a little harder, you want your bottom branch to catch up with the top.
