dried budds

Hello guys, i think that i overwater my plant and because of that my bud on top of my plant is now crispy dried. Bud itself is little moist but sugar leaves crumble in my hand. I want to ask if i should cut it off and let rest to fully flower. Thanks for any suggestions. pic of dried bud pic...

I have two auto white widows which suffered nutes burns. Buds have dried up, except for a few top budds, n leaves have fallen off after clawing. Plants are 65 days old. It happened when i gave em final dose of nutes w water. Any recovery option available ?
