Still clear... it happens quickly when it does happen, in my experience. Over 2-3 days they mature very quickly at end.
Keep eye on it and in more than just the top colas. Disproportionate development on top is a sign of heat or light stress, if the lower portions are riper. If it throws new pistils late in bloom, you get new trichomes on new calyxes that take longer than the rest. Think some strains don't get cloudy at end all the time, too -- sativas, historically? relying on anecdotal info for that, though.
