Leaves folding up dramatically.. humidity?

[FatBoyVik]

Hey,

I have noticed that the latest leaves are folding up with my plants and I am not sure why this would be. I am assuming it would be a humidity issue.

At the moment I have it set to 50% but its 64%RH due to the run off I think. Temps are fluctuating due to the nature of my heater unfortunately but are between 22c and 26c.

I did foliar feed epsom salts earlier in the day so I am not sure this is contributing to the issue?

I have seen this many years ago with young clones but I can't remember If that was too much humidity or too little.

Is this common or something to be concerned about?

Any input appreciated!

Most likely heat. Doesn't look bad though. What's your temps?

 

[FatBoyVik]

OK great, that's usually between 22c and 26c but I'm starting to thing the measurement is off so I will get another and have a look at the temps!

Thanks for the input buddy

If you're using led, you could use to up your temps a bit. Humidity is in a good range, but I'd make sure you're getting accurate measurements.

Sorry you mean use LED to up it? As it's very low in heat for me for some reason.

How close are your lights to the canopy, and what setting, if they are dimmable?

 

[FatBoyVik]

Yes they are dimmable and they are quite far here is a pic. When this occurred they were at 75% of a 600w LED.

I don't think this is a heat issue as its happening again and the temps were 22c with the heater off last light cycle.

Could it be over watering or humidity?

Are you running drain to waste in Coco?

I don't believe so. Humidity seems to be in a good range.

How accurate is your hygrometer?

If you're talking about the tops standing (praying), it's normal.

Get a loupe and look closely for any insects. I see what looks like bits of insect frass (little black dots on the leaves) when I zoom in. Anyway I've had mine occasionally do that under my LEDs. They just seemed happy.

there isnt anything wrong with those plants.

This looks a lil suspicious to me....




Could be normal growth though. Other than that I agree. Plants look good from what I can see.

It’s normal. They just don’t have room to spread yet

Same thing I saw those little black, punctate spots. Hope he checks.

What should I be looking for in the pic is it the shape of the leaf which is the issue like thin ect?
I'm going in now to look for black spots also like suggested here.

Going in now buddy I'll report back. Pray for my babies.

How accurate is your hygrometer?

Not very.. my ac infinity humidifier says 63 but the other says 72. I will get a third and it will probably say a completely different reading..

How about calibrating your hygrometer and then use that to set the humidifier?

Many RH sensors (Pulse, AC Infinity, Govee, AcuRite, Inkbird, etc.) are spec'd to 3%± so, without calibration, it's a real WAG as to which one is "right".

Even after they're cal'd, the update frequency of the devices may be different so if your environment is not stable, you can be gettng accurate values but they might look wrong because of the update interval. I hit that with my 2' x 4' tent - the numbers were all good but the AC Infinity reports every second vs, say, an AcuRite which updates every minute (IIRC).
