Both (in my opinion) are not full grown, they are yearlings/sub-adults... to me when a beardie becomes an adult its around 2 years of age as they still have a bit of growing to do below 2 years.
Basically 1-4 months hatchling, 5-12 months juvenile, 12-24 months Sub-adult/Yearling, 24+ months adult.
Anyway at their age until their about 20 months they should be getting insects daily along with veggies daily. Only one meal of insects instead of two though.
However I did switch my two eldest beardies to every other day insects when they turned 18 months to acclimate them into eating less.
Heres a feeding guide if this helps any.
A young bearded dragons diet generally is about 70% bugs and 20% greens and 10% fruits.
Meanwhile an adult bearded dragons diet is about 20% bugs, 70% greens and 10% fruits.
(This is just a rough estimate of the diet)
All life stages eat 10-20 bugs a feeding.
1-4 months 3x a day.
4-12 months 2x a day.
12-20 months once a day.
20+ months twice a week at the least, every other day at the most.
Staple feeders - Crickets, locusts, grasshoppers, silkworms, black soldier fly larvae, dubia roaches, turkish roaches, possibly earthworms.
Treat feeders - Waxworms, hornworms, superworms, mealworms, butterworms.
Wax worms - once a week, 4-5 max.
Hornworms - every other day to every two days, 4-6 max.
Mealworms - every other day to every two days, 5-10 max. Only for beardies above 6 months.
Superworms - once or twice a week, 3-4 max. Only for beardies above 12 months.
Butterworms - once or twice a week, 3-4 max.
Daily greens- Turnip/collard/mustard greens, endive, and kale if added to a mixture of the other staple greens mentioned.
Fruit once or twice a week - Banana, strawberries, blueberries, blackberries, red raspberries.

You want two supplements at the very least, a calcium and a multivitamin.
Generally beardies below two years need calcium 5x a week and multivitamins 2x a week.
However beardies above two years or at two years of age need calcium only 2-4x a week with
multivitamins 1-2x a week.
This depends on how your adult beardie is with diet, health, just laid eggs, is laying eggs, etc.
