Hi there
They definitely look like she need watering, using coco your going to need to water more frequently then soil, in the picture it looks quite dry,
Regarding a few small roots been exposed I canβt see that being the issue that happens to most people as long as itβs not a crazy amount ..
Give her a good water/feed until itβs dripping out the bottom of the pot then feel the weight of the pot ..
Also as their autos try not to defoliate too much unless itβs really needed/covering buds etc you donβt want to slow them down as theyβre short life cycle.
Best of luck π±
