Trichomes Question

First, I haven't been able to get pictures so you will all have to take my observation which hopefully isn't wrong . I have a critical mass in the harvest window with most Trichomes cloudy, so I flushed it this morning. While rechecking Trichomes again I looked at two of my White Widow plants and like about 20% of the trichomes are cloudy. It's only day 43 of flower which seems early. Are there factores that cause plants to finish earlier? I did stretch vegi period longer, but never heard of that changing flowering time. Could the finish earlier?

I think they just finish when they finish. It can take a long time to get to full cloudy so I wouldn't sweat it, unless there is something wrong with overall health of the plant.
