Scorpion 8 month old not growing???

My friend has two scorpions that are about 8 months old maybe older as his friend has the mother so hes had them as soon as they came off the mums back, but they are still only about 1 inch long is that normal?? They are kept in small plastic cricket tubs cos they are still so small seperatly, fed on tiny crickets every 3 days, sprayed daily and are kept warm. With a bark/ terantula substrate. Is that a normal growth rate??

I think I answered your question on AB. But yeah emps have a slow growth rate. If the temps, humidity, and substrate depth is right and if they eat often they’ll grow faster you can try to turn up the heat to the high 80’s low 90’s to raise metabolism.
