i was told mine was 2.5 years old when i got him and hes 18" but yeah i have a similar problem.
he may eat like a big leaf or 2 and he will taste of somthn and if he likes it he will try a few more if he dont he turns his head to it, i offer him a salad everyday with mealworms(live) and i try to mix it up with rasberries and yellow squash witch he liked the squash and ate a few pieces of that.
i normally only sprinkly calcium twice a month hes got all new lights, and i also see him trying to do pull ups under the
uvb light with the top of his cage. im worried he might fall and hurt himself. hes gotten a lil reckless and knocked over sum of his decor. any ideas add email and ill send pics of my setup
