Is there a Bible verse that says Jesus now knows when the end will come?

[Alexander the adequate]

What was wrong with God's humanity before it became perfect?

Your question is either poorly thought out or intentionally deceptive.
The Bible never talks about His humanity having something wrong. Where did you get that?

 

[Alexander the adequate]

Give chapter and verse, please. Post the words for us all to see.

He must be alluding to Hebrews 5:8+9
