Help with Humidity

I switched my plant to flowering on the 16th of April, so it's now in mid/late flowering. Ever since I came back from leaving the plant unattended for 8 days I'm having problems with humidity. Despite 5 moisture absorbents in my small grow tent RH is between 52% and 60% and usually sitting around 55%. How big of a problem is this? What are some other ways I can lower humidity?
 
I have 3 fans, I use one as an exhaust fan and the other 2 inside the tent for ventilation. Would using one of those two fans as an intake fan (blowing air from outside the tent to the inside) raise or lower the humidity level? Also how can I check for mold/rot problems?
 
If you have a good exhaust you shouldn't need a intake fan but won't hurt to have intake. Humidity in tent always gonna be higher because of your plants. Just make sure you have a few oscillating fans blowing around your plants. You can see white powdery mildew on leaves and for bud rot buds will turn brown and you can take a peek inside and look for mold.
 
I'll try that, but I'm a little skeptical because humidity outside tent is really high too, the weather app is telling me that i have 81% humidity outdoors.
 
if your in a high humid area you definitely need to invest in a proper size dehumidifier for the room your growing in. 40-50% in flower is ideal.
 
I will have to for sure, they are a little expensive though. It's also crazy how at the beginning of the grow I was struggling to keep the humidity up and now I'm struggling to keep it down. A though but rewarding challenge haha.
 
I live and grow in the Smokies, so it's always humid here.
I invested in a 50-pint dehuey a couple of years ago. It's been a good investment and makes keeping RH in check.
I also found that pm and rot are very strain dependent so having a lot of airflow across the plants helps prevent micro-climates in the canopy.
 
Yeah I'll definitely have to invest in a dehumidifier! I opened all the flap and the ventilators create a nice airflow. Right now the humidity is at 52%. Still a little to high, but I think I'll be fine, the plant looks healthy. Hopefully Amnesia is a mold and rot resistant strain then!
