Are these okay?

All depends on your pot size and what your feeding them and how they been trained. In gernal terms, bigger pot = bigger plant, use LST is a good way to help boost yields on an auto, HST not so much. The growth pattern can be from genetics or the light being to close. When the lights to close the inter node spacing "space between new leaves" gets real tight. This is also common on Indica heavy strain sometimes. I would guess anywhere from 1-2 oz on each of these plants if you keep up the good work.
