I’d agree with Michka too - if topping wait for that latest leaf set to fully develop and make the call then. That said, it’s an auto and you won’t have much time before flower and might stress her out. If you go the lst route you avoid the stress concerns and can start training her now. ALTERNATIVE - you could also try fimming her now which would cause less stress than topping and get similar results. If it were me, I’d go with straight lst or fim it now. Following along and hope it helps - good luck!!!
