As far as you green arrow, I’m wondering if the either of the fans are directed at them.
Myself, I’ve not used a fan in many years now, BUT I overclock my extractor fan to bring in lots of fresh air through the passive intakes.
Sometimes, blowing air directly on a young plant can cause the leaf to transpire moisture to quickly, in an indoor environment.
Aiming your fan at a back wall, can help, and you still have your air circulation that can be critical. Once they grow out a few leaves, the air currents become less of an issue, IMHO!
My tip to a new grower, Do NOT love them to death. Water to the weight of the pot, and water to see a tiny trickle from the bottom of the pot. Last, try not to love them to death.
Best to ya!
