Hey, is this Cold Stress??

[MEGA956]

Had the vent directly pointed at that plant, temperature dropped a bit last night (adjusted vent already). I’m wondering if this is “cold stress” and if the plant will recover?

One picture is a side by side with the other plant slightly away from the vent.

I add epsom salt, it leaves those white residue spots, not PM

It sure looks like stress of some type. How cold was it? Maybe it just didn't like air blowing on it like that. These plants are resilient, so there's a good chance it could recover.

It dropped just under 50 f

That's cold. I say give it a few days to see what it does. Maybe lower the lights slightly and avoid other stresses.

at 50f i'd think there would be other plants having issues as well if it was the temp - ngl if i saw my plant like this i would figure it wanted some water. looks just a lil droopy

50 F is not a problem. It will recover.

There was about a 10 year time period where my grow would see 50 F almost every night. The main problem with it is it extended flowering for 2-3 weeks. I wish I knew about these back then:

I just realized that what I wrote could be misinterpreted. By "lower the lights" I meant lower the intensity, which would be using the dimmer to lower the power or raising them physically higher. I need to work on saying that better. My thinking is that the plant mostly just needs a few days of TLC.

The OP also mentioned that the vent was blowing directly at the plant. So I'm thinking there may be more involved than temperature. It could include excessive dryness or wind damage.

a constant wind will stress out a plant and even stunt it..
first i’d checked to see is the plant need a watering?

Unfortunately, the plant did not recover. Watered and gave it a few days, no luck. Gained some valuable experience on this one.

All the other plants are doing great.
