Hey there! Beautiful lady! I think she's ready for some nutrients in 2-3 days. I think the weird leaf-color is due to the stress from 24/0 hour light schedule.
@JandM, no problem, always happy to help out a fellow grower! And for the future, try to look out for the VPD (Vapor Pressure Deficit). You should be aiming for around 0,4-0,8 kPa for Early Veg, 0,8-1,2 kPa for Late Veg/Early Flower and 1,2-1,4 kPa for late flower. Just do some research on the internet, you'll find VPD-tables that tell you what the optimal humidity to temperature ratio is. And as always, happy growing mate 🌱
