So i've been climbing about 3 months now and have worked myself up to 2 days on and one day off at the rock gym in DE. I'm still losing big chunks of skin off my fingers constantly. I've been toughing it out figuring this is whats necessary to build calus and get better at bouldering. Do I have issues with my technique, or is this something that is normal?

its totally normal friend, keep training and gaining finger power and working on your technique.. i suggest you to train 2 days and at least 2 days off, boulder and traverse!
