what is the problem? help me

as regards the wrinkled / rippled leaves of the flowering plants, also in my opinion the fault is of some insect... caterpillars

Yes, the only affected leaves are old and lower...

Don't worry so much about older leaves. It's the news ones on top that count.

It's better to feed lightly more often than heavy once in a while.

ok, I'll try to slightly increase the dosage/frequencies of the fertilizations, hoping that the deficiency does not progress...
