Tami... Thats not good, sounds like mold... are there any of the leaves that are turning tanish and curling right near the problem? if so, cut out the infected bud an inch below the discoloration... u can let them grow on, toward maturity... u didnt mention how much longer to finish... I have taken all my big buds early before , as not to lose them all to mold, then let the rest go to finish. good luck
