can the fan cause the plant to have issues? I alwa...

I always tend to point my fans at the sides of the tent so the air hits it and bounces off around the plants... With a scrog net, you can also put the fan to work underneath the canopy - again, not having the air hit the leaves directly... try either of these and see if you don't see some improvement! Good luck!

I find it best to have the fan blowing across the top of the plant but not directly hitting it.

The fan should not blow directly on the plant. It just causes the plant to work harder to keep her leaves pointing towards the light. The fan is just needed for air circulation inside the grow space. When the leaves gently dance in the wind it is perfect. It will make sure that moist will not sit still and cause mold, to cool the plant down and let the water that transpirate from the bottom of the leaves evaporate. Wind pointed directly on the plant will cause unnecessary stress. Your plants are looking great! Enjoy your grow buddy!
