Average Humidity is 25-35% in VEG. Help!

My average RH is 25-35% in veg.
Avg. Ambient Tent Temps: 72-78
Avg. Leaf Surface Temps: 80-84

I am using a grow tent 64" x 36" x 20"

6"x16" phresh filter 200cfm

4" VenTech 190cfm pulling from filter

Also a 6" Growbright inline fan 424cfm pulling from Air-Cooled Tube exhausting out my window

I have one of my girls tacoing downwards, looks like its getting a lack of Nitrogen because the leaves have turned from a lush green to a more pale green, with light browner spots, and spots of darker green. I overfed her last week but changed the soil-less mix.

Will post pictures later.

Whats your soil ph, and nutrient ph

Nutes pH were 6.7 (pH perfect sensi)

Runoff around 6.4

Using sunshine advanced #4 with about 30% more perlite

hate to say it ,but it looks like its a case of poor genetics. i keep hearing people talk about breeders almost refuse to stabilize a trait before advertising.its a money thing.

Your RH is fine at 20%, obviously higher is better but it's no the cause of ur problem here..maybe back off the nutes for a minute
