Giving more light?? PLEASE HELP

Hello all i currently am in day 51 of my autoflower grow and i am in late flowering and have noticed mold on my plants. I am a new grower and dont have much experience. I am growing 20 of these plants and feel they are going to be ruined quick if nothing is done about them. I am currently running my lights 18/6. I wanted to harvest early or on time i was wondering if i could switch my light cycle to 24/0 or 20/4 without anything happening? Anyone have any ideas or input?? I need help quick

I dont know much about auto strains but shouldnt you be running your lights 12 and 12 in flower? And a dehumidifier may help with not allowing more mold. As far as the existing mold Im not too sure brotha

Moldy nugs are never good bro, too humid in your flowering room. How moldy??

Do you have a fan blowing at all times that is a must. Hang sum clothes or blankets in the room and they will absorb sum of the moisture, Dont leave standing water or open containers they evaporate and raise the humidity. Ive never had an auto flower so your on your own with the light question heee.

ya, you really can not go wrong with giveing a plant more light, especially during flowering.

these are the pics of my moldy plants

how humid is it in your grow room? mines at 60% im worried..

well you need to post up your rooms temp and humidity?

Man I assumed you had bud mold, but thats powdery mildew. They make products to treat that just google powder mildew.

yea i doubt what your looking at is related to your light cycle. and i thought you had some bud rot pics for us. why aren't they in 12/12?
