@symbiose089, Just a small fan of any sort/size, gently hitting the plants during night, all night, you don't necessarily need to open more vents. Whatever size your exhaust is you want a smaller intake at the bottom of the tent, this will give you a negative pressure whenever you exhaust. . I have a 4" directly sucking up air from the floor in my basement with 6 sets of lungs in my home I easily keep co2 1000+ppm, this is my intake (ALWAYS on during day) literally a15$ fan off Amazon. Co2 for daytime, No co2 needed for nights.
NIGHTIME: 6" exhaust up high, this exhaust should be set to come on at 45%RH and stop at 40%RH, have this set up for nights, very simple logic, drier the air, more space for the plant to spit it out, you have don't have to be so rigid with 40-45, try 45-50 or 50-55, whatever works for you, if at night air dances around 60% or higher, it will start to negatively affect the rate of perspiration, at 70% the plant will close its stomata and production will cease, none of the light energy processed throughout the day will be converted.
Don't worry about leaf mass, after the stretch nothing new in terms of the "new stem" is made, so what seems short and stalky now will "stretch" into lovely clusters later in flower. May look short and stalky now but come flower that's what makes dense cola. Green light penetrates 6-7 layers, blue and red only 2-3 at most, this is essentially what causes popcorn buds, in future look to add supplemental side lighting of red and blue, this will give the green that penetrates 7 layers from up top the correct ratio of rbg 1:2:1 needed for correct bud development.
