Hey there , humidity goes up and down with your watering cycle so just be aware of that fact whilst taking measurements. Basically it's no harm done at this point. The main reason why folks like to get lower humidity is because they're tryen to prevent like fungus, rot, and even bugs that seem to thrive at 65% . Another thing is that trykes pop out a bit more in lower humidity levels. you're on week 3 of flower so try to dial in your humidity and temps - that can go a real long way towards your yield ! If you have good air circulation already not much more you can do except : make sure the exhaust goes out the room completely, or add an air intake or increase the air intake with cooler drier outside air. The demidifier works too, but i don t use one. Better safe than sorry bro - you want to get on that ! dassit 🚀
