hi, the strain is paia hawaiana from sativa seed bank. its a pure sativa strain so ive heard that the flowering period should be more than two months. well, the plants have been flowering for about 67 days now. the seed packet said to flower them from 57-64 days. the pistils have virtually all turned brown, but the flowers are all looking a bit skimpy and i cant see any signs of trichs turning brown. is this normal for a pure sativa? what should i do? cheers weedboy. btw, i have a bit of a spider mite problem
