Looks like she is starting to flower already.

Hey man, that is indeed grey mold aka Bud Rot aka Botrytis Cinerea - its species name This was caused because of how high the humidity is in the tent. 70% is way to much for a plant in later flower. You want to get that level down to aorund 40% This is a handy little tool to reference, It shows you optional ranges of humidity in your grow for the temps your pulling. https://www.dimluxlighting.com/wp-content/uploads/2019/02/Leaf-Vapor-Pressure-Deficit-VPD-1.jpg The chart is called VPD,or vapour pressure deficit chart. Ideally you should aim for 24-26c temps but that's not always possible. Defiantly want to increase the air flow in the tent and lower that RH down. If you need you can use a dehumidifier to help with this. Or only grow in months where humidly is lower for you if the above are not feasible options. Chop off the rotten bits, and keep going till your ready for harvest, Keep a close eye out for more of it. also after harvest when your drying it and curing it. Best Of Luck and Happy Growing!
