Thanks... I read about botrytis. Although the top of the bud, brown hairs and dried up brown leaves, it does not seem to have any grey or other colored fungus/rot. The bud feels dry on the outside, but it's moist inside. It smells heavenly.
The other buds have just the white and brown hairs and look fine, except some of the have the same few dried up leaves at the top. There are a few leaves with yellow blotching on leaves/some few have also yellowed.
Conditions in my grow were okay except that the PH was a little high, 7.2 until about two weeks ago when I corrected it down to 6.0
My growing area is 2 x 4 grow tent where there are 6 plants, 3 strawberry kush, 3 diesel. 400w MH/ HPS 18/12
If I loose this crop I will be crying for months and I will need anti-depressants.
