Having some trouble reaching the g and d strings cleanly. Been taking lessons for a few months. Can you help? Thanks.

Make sure you press your fingers down hard on the string and try not to bow as roughly as on the higher strings if that makes any sence?

Keep your left elbow below the violin. think about it coming around to the other side and use gravity to keep it down. Asking your teacher may also help. This is a common problem that will be solved through practice. It's better to solve now than when learning 5th or 6th position!
