Any idea why it's white? Is it normal? I do have her under a grow light. Water her when fully dry. Is it normal new growth or could she be too close to the light?

I just saved this cactus from my grandmas house from what she said i think she maybe over fertilized him, and kept him in a non drainage hole plastic pot. i let him sit for 3 days to get used to his new environment. just today i put him in a new unglazed clay drainage pot…. i noticed when repotting him his roots were a bit orange but long, most of his spikes are black and, he’s also partially brown.. my question is i guess if theres anything else i should do to save him?
