Variety is key. These pellets may be designed to have all the nutrients, but think about how quickly a person is bored with the same food over and over again. Bearded Dragons are very curious creatures and like/need variety. Although I do think these pellets are ok, please make sure to feed a good variety of vegetables as staple with some fruits with these pellets. Mixed greens are not expensive and if you find a place where you can buy them loose (Whole Foods or so) you will find to be able to buy small amounts for little money. In addition for a baby/juvenile make sure there is real sufficient protein intake. If you do not like life crickets or worms try canned or frozen, you can get them from Amazon fairly cheaply. Very important to provide the correct heat and lighting (including a good source of UVB) also, as without a 100F hotspot your dragon will not be able to thermo-regulate and digest properly.
There are very good tips and pointers for affordable food options on this site.
Best of luck to you and your dragon!
