sorry been a little busy, ok the first 2 are northern light autos, there really flowering nice the next 2 are short bushy sweet tooth auto there about 2 weeks behind the northern light autos but are really starting to look nice now. this is the first time I've done the auto sweet toothAre these all the same plant? (Hard to tell sometimes) - also, is the first picture on the left Auto Sweet Tooth? If so, DAMN.... yours is MUCH more bushier and compact than mine was. Mine was about 4' tall with many side branches... acted like the only light it wanted was around the corner! Ha
