What was you RH prior to it? Very low humidity can cause the plant to rapidly uptake nutrients from the roots, which can cause some burning or other leaf issues. If it is too high, that will slow things down.

New nutrients, are they a similar ppm and PH to the old water?

Maybe try playing with the placement of the humidifier but the RH without it is very low and can cause issues. Low humidity causes the plants stomata to open and transpire continuously, this requires the roots to rapidly uptake water and if the PH is out of whack or the ppm too high, this will be a problem.

So I'de encourage the humidifier, but try and aim it off a tent wall instead of at the plant. Better yet, if you can humidify the lung room and then draw in the moister air through your intake. For veg, 60-65% humidity isn't uncommon.

The PH sounds good for that sort of system. Some people will run at 5.8 too.

My opinion, if your pH really is less than 6 in hydro, you should be OK. I'm with @Chad.Westport , I believe your issue is humidity. Chad has been handing out all kinds of great advice today.
