I've done that a few times as well and it never gets above 92 without a cover over the thermometer. There were some hairs turning darker on the lower buds of those same branches. By the time the light went off yesterday, some of the buds on the other side of the plant had started as well. The second largest plant, which looks a lot different than the others, has a few purple hairs or really small leaf tips on the top and the larger leaves around it. The other two are really short but are producing some super stinky and resinous buds.
