Non serrated autoflower leaves

The development of non-serrated leaves near the top of cannabis plants during the flowering stage, especially around buds, is fairly common and generally not a cause for concern. These leaves are known as "sugar leaves" because they are often coated with a layer of trichomes that look like sugar, like yours. If you observe that these leaves are significantly different from what you've seen before, it could be due to a plant hormones: Sometimes, changes in leaf shape can be caused by fluctuations in plant hormones, which could be induced by a variety of environmental factors or the plant's genetics. As long as your plant appears healthy otherwise and there are no signs of hermaphroditism (the presence of both male and female flowers on the plant), these non-serrated leaves near the buds are likely not a problem. Continue to monitor your plant and care for it as usual. Good luck !
