i transplanted a week b4 flowering into a 4 gallon pot, and used some vitamin B1. the strain is "NYC Diesel" (mostly sativa, i think). but the leaves are not yellowing, they're completely wilted.
it's happening only 2 the fan leaves. the new growths appear to be healthy and green, and it is budding.
i'll borrow a camera and post some pics in a couple hours when the lights turn back on.
