I am not an instructor, but my two cents worth anyway....
Yes, a conversation would appear to be in order - prepare to take a few notes. Your instructor must think something is missing/inadequate in your skills. If you have yet to be trained in engine failures, that would be one important thing! You instructor has the responsibility and opportunity to assure that you are not sent first solo until the conditions align well for you (but cannot guarantee an engine which will run the whole way 'round!)
I would expect that there is a skills checklist which must be filled before first solo - what's not checked in your case?
At this phase in your training, avoid receiving training from multiple instructors.
Good luck, let us know how it works out....
