I have added some pictures on an issue I'm ha...

hey there, i see what you're showing me on these pics, that's basically that's standard calcium deficiency. You can tell from the rust colored spots on the leaves. This came about because of the intense light schedule, the plants went into overdrive and needed more micro nutrients like calcium, problem is plants aren't all that great at absorbing micro nutrients through their roots, which led to a deficiency. You need to add cal mag to the feed every so often. Since you're showing signs of a deficiency, i would suggest also a foliar spray, just try to avoid getting the buds too wet. For the spray usually you put 2 ml per L and spray on the leaves at daybreak. Hope this helps ! 🚀
