Looking good for the most part! they are growing very fast and are overall healthy although I think they may be getting a bit stressed from excessive wind/heat but that doesn't seem to be impacting the rate of their growth.
First of all, thank you for your desire for preservation. I think there was pollen contamination. In addition, you did not come across very interesting phenotypes. But I advise you to do it again because you have the skills to cultivate pure sativa.🙏😉
