Yellow mottled leaves with burnt edges

heya indianqueens , you have pretty severe magnesium deficiency you can tell from the yellowing on the serrated edges of the leafs and a bit of N deficiency which you can see from the yellowing of the oldest leafs first, and calcium deficiency which can you see from the rust colored spots on the leafs . The best thing you can do is to add cal mag or epsom salts as well as some NPK. Hopefully if you do this the problems will stop spreading and the plant will recover in two weeks or so , hopefully. Hope this helps ! 🚀
