ok so this is Purple Kush Auto and it's about 10 weeks or so in. I noticed some brown specks on the leaves closest to the cola top bud. But otherwise the rest seem healthy. Just one other leaf on another plant has a brown tip from awhile ago and hasn't changed. I feed twice a week with plain rain water in-between. Using gold leaf fertilizer and once a week molasses with microbe stuff. Ideas or is this normal?
