Yeah, I wouldn’t add more moisture personally. Even at a young age around 50% RH is fine in my thinking. Powdery mildew can catch on a plant when the atmosphere is too damp with not enough air flow. Stagnant wet warm air harbours a lot of life. I’m probably telling you things you already know..
I’m assuming you have enough air movement in there? Not just the exhaust fan but a clip on rotating the air around?
