Is there a problem light sugar leaves and clear gel type liquid

Is it normal for my sugar leaves to turn a really light colour not many at all but a few buds have really light leaves underneath the buds also some very light purple I have attached photos. They are very nearly ready for harvest so I'm not worrying too much but today I also found a couple more of the little gel like droplets underneath a couple of the lower buds. Can anyone shed any light on what the liquid is it's really sticky but oily aswell. ?

That looks like it could be beginning bud rot.
So be aware of RH and air circulation if indoors.

Not sure what droplets could be?
