Looks to me like you just need to feed more nutrients. You don't want water on the plants when you have intense or powerful lighting on above them. Think of ants under a magnifying glass. The leaves are the ants and the water droplets are the magnifying glasses.

As stated by @bk78 light doesn't magnify water drops and burn the plants. That's pure perpetuated bro-science.
Also you could have at least said thank you for the PM I sent you.

Be careful OP bk78 doesn't know what he's talking about, don't spray the plants with the light on.

Advice like this will mess up the OP plants.

That article would explain all the torched plants outside that the sun beats down on after it rains right?
You should go focus on your own torched plants. Or is it all dialed in now?

Outside there more airflow, and the clouds shield the direct light from the plants
The light intensity drops on a Cloudy day.

yeah bro...I just was looking at your plants dripping in liquid. The light is going to torch the shit out of your plants with all those drops on your leaves. Try to only foliar spray like 15 minutes before lights off, and when I do that I usually dim the light down a bit too. Gives them time too dry up a little bit with lower powered light and the fans going before the lights go out. By the time the lights go out they will almost be dry...that way you don't have to worry about mold PM or anything. And I don't really suggest foliar spraying anywhere after middle of flower. Could cause bud rot.

I spray all my plants with some kind of IPM weekly during veg and always do it with the lights on, I've never had any issues with burning. I don't spray in flower unless I have some specific issue because the humidity it creates could allow some pathogen to take hold. If you have some botrytis somewhere, it will spread with the water like wildfire.

As long as you have good fan airflow then they will dry right up without burning them. I always give them a good shake too after I spray to make sure there is not any large drops on the leaves. The water drops intensify the light...acting like the sun ray through a magnifying glass and burning your leaves

And what happens when the clouds are gone and full sunlight hits the beads of water on plants?
They burn right?

In general veg lights are weaker and the plants replacing the leaves, spraying a hot canopy can cause lots of damage and under hps it's really dangerous.

I mean, yeah, you can get away with foliar spraying with the lights on...but that is also depending on a lot of factors. Humidity, light intensity from your grow light, if your shaking them off after, how much your spraying, and especially what you are spraying. You can also spray in morning right when lights go on and dim them a bit for a half hour or so and let them dry. Then put light back up

Are you comparing my 12" fan compared to the strong wind after it stops raining lol

Look the bottom line is, a new grower cold walk into his hot flower room, low humidty and spay the plants, thinking this will help, it could mess his canopy up, basically spray a hot canopy is bad advice.
