CBD charlotte's angel grow

So the buds have started putting on the weight. My humidity has spiked for a couple of days. I started seeing PM on some of the plants. So I did the last lite defoliation on these ladies to remove the infected leaves, improve light penetration to the lower buds and reduce RH. The tent smells so sweet, citrus /fruity scent. The buds are becoming frosty and pistols starting turning brown.
