During our convo with Juvenile, the OG of the bunch assured TMZ Hip Hop their reunion tour is still going down, as he plans to put his "big brother" peer mediation skills to work.

Juve believes the CMB crew just needs time to cool off -- but, as for how long that will take ... whoadie that's another story!!!

Turk was confident in telling TMZ Hip Hop a few months ago that the original Cash Money cartel would be taking over like they did in '99 and the 2000s ... but B.G. kicked off the year throwing shots at Lil Wayne and apparently, Turk needs a make-good himself.

Birdman's brother Terrence "Gangsta" Williams recently speculated to DJ Vlad that Turk would have to distance himself from Birdman if the tour happens, as the CM boss is still upset over Turk's bean-spilling "Drink Champs" interview from a couple years back.

Returning to the basics could potentially squash the posse infighting ... Juve's re-releasing his "400 Degreez" on March 29 with a pair of new tracks named "Party" and "We Be Blowing Money" and fondly recalled memories of making the classic album.

Juve didn't have an explanation for why there are several variations of his breakout single "Ha" on the project, but he's happy he took a gamble on rapping over a Latin track where he won big with his "Follow Me Now" hit.
