These plants are doing so well. One plant is stretching a lot. All the flowers are starting to get a lot fatter. I will start checking trichomes next week as I can see a lot of them forming on the sugar leaves already.
Your leaf is turning pale as the upper fan leaves are blocking the light from reaching it. This is resulting in a loss of chlorophyll which gives the leaves its green color.
Man, the idea to cut them might be very seducing but it would be way too early, if it's 60-75 days by passport no way it would finish in 5 weeks of flowering, buds look immature and there are too many white stigmas in my opinion, I personally would at least give it 3-4 more weeks, the more the better, wait and see! It looks like it would be an excellent harvest, they bulk up pretty good IMHO. Saying as someone who is guilty of too many premature harvests
