40%

Just wondering how critical the 40% or lower number for humidity is when in flower? Assuming a fan is running non-stop and the humidity is occasionally over 40% (say 45-47%) is that going to be of serious concern?

I have two seedlings that have been growing for about 2 weeks now, one of the seedlings is drooping quite heavily (it was overwatered) but it was already starting to droop. My second seedling is doing okay but I noticed today that some of the tips of the plant are turning white. I use a 400...
