Ludacris can't afford to pay thousands of dollars in child support -- and he's blaming his financial woes on the death of his "Fast and Furious" co-star Paul Walker.
Ludacris was in court Wednesday with his baby mama, Tamika Fuller ... who's demanding Luda pay her $15K a month to take care of his 2-month-old baby daughter, Cai.
But Luda went to court and told the judge ... he was counting on "Fast and Furious 7" money to make his payments, and the movie is now on hold so his payday went away.
Luda claims he can only pay $1,800 a month -- confessing he only made around $55K for 2013.
The judge split the baby down the middle, ordering Luda to pay 7K a month for now ... while hizzoner reviews all the financial docs.
By the way ... Tyrese also claimed relative poverty in his child support case because of Walker's death.
Paul Walker Dragged Into Nasty Custody Battle

Tyrese Gibson claims his baby mama is using Paul Walker's death to shame him in their child custody war ... TMZ has learned.
Norma Gibson filed court docs claiming Tyrese is a bad dad, who should have stayed in L.A. to spend time with their 6-year-old daughter after Paul Walker's death ... because he had time on his hands since "Fast & Furious 7" was put on hold.
Norma says Tyrese blew off his little girl, choosing instead to go "gallivanting throughout Dubai ... staying in expensive hotels ... partying on yachts, sky-diving with other movie stars, driving expensive cars, and making special appearances in night clubs."
But sources close to Tyrese say he's indignant Norma is using Paul ... and he went to Dubai on business. He had 4 gigs and he needed the money -- ironically to pay the child support Norma was demanding.
The court battle rages on later this month ... when they each try and convince a court-appointed child evaluator who's good and who's evil.
