$6,000 to use in my Roth IRA. 6k to invest - 50/50 QQQ and VOO a good idea?

I have $6,000 to use in my Roth IRA. 6k to invest - 50/50 QQQ and VOO a good idea? I already have 14k in 2 dividend stocks in that Roth IRA that I’ll keep for now. Also have 57k in AMZN and UAL in a normal brokerage account. Will probably shift all those to growth later on. Now I’m trying to shift to more growth as I’m only 24. Open to other recommendations
