Curious question about humidity

Hey guys , so I recently changed around the setup of my tent . Bigger fan and more air being pulled out . I'm noticing the plants are drying faster than normal because of the drop in humidity and are needing to be watered more often . Would this coincidentally be how you feed them more to get them to grow faster etc ? If the soil dries faster then need water/ food more afternoon and grow better ?

There comes a point where the humidity is so low that transpiration happens faster than the leaf can use the nutrients in the water. These nutrients pile up and eventually become toxic and poison the leaf from the edges in.

Too much humidity and there is not enough fluid exchange through transpiration causing the leaves to look swollen and deformed.
