Spots, curls

How often do you water and how much are you watering. With the yellowing droopy leaves and can’t seem to figure out what’s going on have me leaning towards root issues, Cannabis root rot can cause leaf symptoms that can look like almost anything: cannabis leaves get burnt edges or tips; yellow / bronze / brown spots or stripes; nutrient deficiencies; clawing and curled edges; and other unusual leaf symptoms. hope that helps

The girls look very droopy so my insticts think light. I've had the lower leaves do this through lack of watering so......... They would be my initial research. But then they do this at the end of their life cycle too...

When it comes to drooping, if she peeks up an hour or two after the light comes on, she's fine! If she's always drooping you may be overwatering. At some point during flower, she will start using less water, so pay close attention. For the leaves... well it looks like the affected leaves are in very shady areas, so this is probably the cause. The taco shape is light or heat burn almost definitely. Any other issues may be connected to a calmag deficiency or too much N. I would start by calibrating your pH meter and making sure you feed and runoff are in acceptable ranges. Seems like a lot of issues, I know, but they're all easily correctable! You got this!!!
