I think I see what's happening here...This is probably as good a representation as I can get of all four fans and one humidifier lol. With that humidifier going, the current temp is 73 F and 54% RH.
So, you're pulling in that water vapor from the intake and I think it's probably getting trapped around the skirts of your plants.
If you've already just adjusted it, see how that works... if not... I would try, if possible, to get that lower clip-on fan below the canopy so that it can circulate the air underneath all the leaves and swirl it around to subsequent fans that take it upward... something like so.

Temps have definitely dropped from 82 F to low/mid 70s lights on. The humidity has dropped lower than it should (hence the humidifier).Has the airflow changed at all?
Temps? Humidity?

The clip on fans were lower and I moved it up when I added the external fan to increase passive intake. Both humidity and temp dropped after I added the external fan and that is that is why the humidifier is now added.I think I see what's happening here...

Also can’t get the fan below the level of the canopy without hitting the plant’s leaves or basically blowing it out the intake flap.I think I see what's happening here...

Yeah, my thinking was just to get the plants transpiring a little better and maybe perk them up a bit more so they're not laying on each other.The clip on fans were lower and I moved it up when I added the external fan to increase passive intake. Both humidity and temp dropped after I added the external fan and that is that is why the humidifier is now added.
It'll also help move around some of that soil evaporation.
Hmm... that's a pickle.Also can’t get the fan below the level of the canopy without hitting the plant’s leaves or basically blowing it out the intake flap. View attachment 1067384
I'll keep thinking on it.

Are you running a carbon filter?... Only ask because blowing like that last pic would screw up the effectiveness.

Took the lowest fan off its clip and attached it to the pole facing the front door of the tent and bouncing the air off that wall. I guess I’ll see how that goes.

Of course now the temps are higher and the RH down too low because I’ve turned off the external fan and humidifier.

I would leave those on. I was only looking to kick up that surface moisture. I'd believe - and I could be totally wrong - that everything was good except that the moisture was allowed to settle at the bottom.Of course now the temps are higher and the RH down too low because I’ve turned off the external fan and humidifier. Boo.

My advice... Put everything back how it was... Everything is looking great.
To address the condensation you were concerned about, just brush through the leaves with your hands once or twice a day.

What if she lowered the carb filter?
Obviously it would need an exit hole even with the output of the exhaust fan.. i dont see that possible. Unless a raxial was installed that would help a lil bit....just ideas!

I would like to offer my apologies for being bitchy earlier. Side conversations and digressions I love and encourage...as long as the need is also addressed. I’ve had to corral toddlers, children of all ages, and delusional adults trying to extubate themselves, so the “listen up!” tone is well honed and sometimes in excess. Please accept my apologies.

When possible, I like to exhaust high and intake low.
That said, my current 10x10 had to be done differently.

This is the approach I’ve taken and it also maximizes available space in the tent.When possible, I like to exhaust high and intake low.

I don't know if I subscribe to the no direct air flow thing. I have a 5'x5 tent. I've always used an oscillating fan, and haven't seen any issues. Granted, I do run it at low speed when they're small. Besides my floor standing 16" oscillating fan, I have a 12" hanging from the top supports. I used decent sized zip ties with enough slack so I can slide it from side to side if needed. The 12" is pointed slightly above the tops of the plants, and is usually centered on the plants.The filter is as high as it will go. Believe me when I say I have sought the input of and implemented the suggestions of the wise ones here on airflow. My tent is little. 36” x 20” x 63”. There is no way a single 16” fan would fit lol.
When they're seedling to small veg I usually run just the 16". As they get crowded and start flowing I start running both at the same time. Just another way to get down the road... I bring up the top mounted approach because I've seen a pic where the guy hung what would normally be a floor model upside down from the top of his tent.

I tend to agree.
My plants get that water build up too if the fan is off.
You’ve seen my grow Amy. I’ve got the fan right on my plants, although I dunno if it’s because the Dyson style of fan but I can crank it up pretty high before the leaves curl.
The indica could take a bit of a breeze. They are used to growing mountain sides no?
