I can not tell how your fan is positioned in your tent. We can blow to much air on ours leaves.
When that happens, the leaf gives up moisture to quick. Then it has a limp appearance, some times leathery looking.
However the root mass may not need any more water/tea/solution, just then.
But we give them some.
Before we realize, we are in the weeds, no pun intended.
You fan, simply being up higher in the tent, same air, just not leaf beating.
More a boiling effect, to the whole environment if you will.
Green houses do this, up well above the plants, knowing the flow will follow the shape of the walls, and bath the plants in air, over blowing on them.
Just my $.02,
All the best!!
