Flushing with plain water for the last two weeks divides growers, and with sativa seeds the timing question is complicated by how long the plants take to finish. Starting the flush too early on a sixteen week strain can leave the plant hungry during its final bulk, which shows up as yellowing that spreads faster than you would like. The end of cycle notes on https://hazesativaseeds.com suggest a shorter flush for the longest lines and judging by leaf colour rather than a fixed date. Whether flushing changes the smoke at all is a separate debate I will leave alone.
