Humidity will jump up, you're gonna need a dehumidifier or you'll risk bud rot.

Looking good! First time? Keep the humidity between 50 and 60% and your temps between 70 and 80 degrees and you will be in the VPD green zone the rest of the way! Google that if you think I'm speaking in tongues lol

Move the temp and rh monitors you have now away from the soil and up to where the top leaves are. Don't mess with them too much...less is more. Looks like they are going to get hungry if you just flipped them. If you want real helpful hints from the folks who really know...start with this....

Oh there is a change alright...and would b very noticable with more plants in the room.im a noob and noticed ive gone from using humidifier to not using one..your lights off is the most important..whether using a dehumidifier or extraction fan to bring it down.im using extraction fan atm plugged into an inkbird and also have an 100 watt reptile light in there to keep it around 18 -19 deg overnite .some days the humidity is higher outside and struggle to keep it under 64%..i do have a dehuey but havnt set itup in there yet...good ones a pricey..i think i payed 400 bucks and can can collect 10lites a day...i reckon you will get away with just using your extraction fan and make sure it doesnt drop below 17 deg..my humidity stays around 56% atm..will get that down more later in flower to 45-50%..mine droop under that but stand up nice 0n 19 deg c..

I run my lights through the night as it gets cold here...my room keeps at a constant 24.5 - 26.1 before my extraction fan cuts in and extracts air for about a minute back to 24.5...humidity gets to 60% at 26.1 and down to 45% ..at lights off i plug the extraction fan into the inkbird dehumidifier and set to 56% some days it just wont get to 56 and the fan stays on continuously and that make the temp in room drop too much and they dont like it..hence i put a reptile ceramic heater in there to help out.ive been getting away with the extraction fan but i gotta get the dehuey in there soon..i did put it in there but it didnt work but i couldnt see shit as the light was that bright on the dehuey i couldnt see the illumination coming from the dials lol...

You can get a free light meter app on your phone to check light distance. You want 65k lux for flowering. Over 75k you should avoid, that would mean the fixture is too close or should be dimmed.
