I think I’m getting decent yield on my little girls until I see some of y’all’s pics! Since there could be multiple reasons for my small yields, what change(s) should I focus on potentially making first?
Fimming/topping and LST are methods used on auto for yield. Timing is paramount with auto. You need explosive growth and little stress. Large veg before it flips itself. I suggest slower starting with advanced methods on auto till you are comfortable getting them to the finish line. A photoperiod will give largest yield with less stress. Pot size helps. Larger pots tend to give bigger plants.
A good light is probably the single most important part of the equation. Training,nutrients,environment all play a big role as well but that light is the key to success
Looks to me like you have insufficient lighting. I would say based on your pics you need at least 300-400 true watts of good full spectrum light for those 3 plants.
It’s multiple things Growmie but the big 3 are lighting, environmental conditions and nutrients
