Yellowing burnt crispy leafs from bottom up? (Outdoors)

La nuova crescita è sana e questo di sicuro è rassicurante😂😂 Possibile che quelle foglie siano state a contatto col terreno bagnato quando hai irrigato precedentemente? Comunque le toglierei... magari aspetta qualche giorno che i rami crescano un po' poi toglile...

That might be an infection? LOL, that looks horrible. If it were chlorosis starting at the bottom, i'd say n-deficiency but all that black blotchy stuff is a bit too much. Are you keeping an overly wet root zone by chance? If you don't have a good wet-dry cycle, it's probably a pathogen of some sort. Even if a P or K deficiency was coinciding, it still doesn't look right for that, either.. that could add some dark blotches and such to the list of symptoms. did you re-use soil? Using some weird foliar spray? It's outside so disease is a bit more of a concern than an indoor context. Nothing to lose.. try upping the concentration of fertilizer a bit and see what happens. I'd isolate it from other plants, if possible, in the meantime. If not allowing a good wet-dry cycle with your irrigation, also start doing that. It should never wilt, but it shouldn't be saturated 100% of the time, either.
