Drying, humidity dropped to 51%, problem?

Day 9 of drying in tent. When I left it was 61%. I was gone for 7 hours & humidity dropped to 51%. Is that a problem?

Anyway i got the humidifier back on now in my room. Looks like i may need to put it in the tent, with my weed to get it all the way back up to 60%. Should I do that? I just figured cool mist humidifiers running right under my weed might breed bacteria/mold, so I've kept it outside my tent so far.

If it was just the environment in the tent that dropped to 51 for a short time- you should be fine- no more than 62 in the jars
