Is it common for kids on ADHD medication to have growth/weight monitored differently than adults?

Yes, because stimulant medications' appetite-suppressing effect can affect growth in children specifically (not just weight, but height trajectory over time), pediatric ADHD medication management typically includes more structured growth monitoring (height, weight, sometimes growth charts tracked over time) compared to adult monitoring, which tends to focus more on general weight and appetite rather than growth trajectory.
