If I'm correct depends on the stage if veg it looks like severe mag def and if in flower phosphorus def Sent from my SM-A025U1 using Grasscity Forum mobile app
Prolly more than one thing. Looks like at least phosphorus. What kind of media, what are you feeding it and what stage of life is it in? Picture of the plant would be super helpful. Just diagnosing the deficiency won’t really help you. A hungry plant or a plant that’s overfed to a point of being locked out or a plant with a pH problem can all produce leaves like that. We can guess at what nutrients your plants aren’t getting, but we can’t help you figure out why they are doing what they are doing without more info. Cheers
