yes,I've just harvested one zkittlez.ccheck out my diary.it loves defoliation.whatever is blocking the light,I remove it.I do it throughout whole grow,except vegetation.It seems to be working better in flowering,especially early flowering just like your.And yes yours need to be defoliated some more by the pictures.I would start with lower fan leaves at bottom to create space for air circulation because you are in a tent,slowly go towards the top as time passes,later in flowering.
