Plants are doing much better since raising the light, new leaves are looking much better than before this change, happy with the growth this week can't wait for next week
Hi mate @UkGrown This is really cool genetics. Please check you PH and your water intake. And then the light and heat stress can also cause this problem that I can see. Start with PH and make sure you do not over water. Check the temperature as well HID is hot stuff. Hope it helps. Good Luck!
