Yeah I saw that and it's not okay; you could end up pretty fucked mold-wise.
You're in a basement. Look to your FLOOR as a source of humidity. You're gonna want to seal any raw concrete with a nice heavy coat of waterproofing paint. I used plain ol' KILZ oil-based primer, white. It may make you pass out from inhaling kerosene stanky paint fumes but it did a good job on my cellar floor.
Double-check that your hygrometer is working accurately. Thos echeap walmart ones aren't all that reliable; I've got 3 identical ones and they NEVER all agree lol!
Exhausting air more aggressively will also draw your humidity down. And a small space heater will lower the RELATIVE humidity.

Okay, yellow plants. Hm. Has anything else changed other than the light cycle? pH still stable?
