2 seeds - Sensi Skunk Automatic

I'm at the end of week nine and the pistils are browning. It could be light stress or it could be the buds are reaching their time. The problem is the buds look tiny/non existent, perhaps because I don't know what I'm looking for and I can't see the wood for the leaves?

Hi, another harvest question! 12the week of growth. Some buds have, say 10% amber trichomes, others all milky. I'm keen to get the plant out of the grow tent as it is blocking the better yielding plant. Should I harvest or wait a little longer?
