Starting an Oil Painting at Low Humidity

Hello everyone, I hope you’re having a fantastic Monday 🙂

 

I have a question about an oil painting I’ve started. I painted a thin layer on a lead primed aluminum panel about a week ago. I wanted the layer to fully cure before continuing, but the ambient humidity has been low, between 28-20%. The temperature is already carefully controlled, at least now, but I wanted to ask about this humidity. I am trying to slowly raise it to 45% over the next 8 days. In the time since I began has any kind of damage begun? I haven’t noticed any but I’m asking because I suspect this kind of damage can’t be seen right now

 

The only other relevant information (I think) is that the studio is between 18-24 celcius/75-64 Fahrenheit, and it could drop to the low-mid 50’s while I was away for my work shifts during the week (it would naturally be raised back up to a good temperature over another few hours) but those swings won’t happen anymore, the temperature will remain stable and the humidity will now slowly rise and stay at a good range.

 

Do I have anything to worry about?
