What mars hydro light do you have? Do you keep it at one setting or gradually increase it? I didn't find any difference in increasing the distance of the lights.Aye! I read the whole post but to me it looks like your LED's are just too close/strong. My Marshydro needs to sit at 36 inches or I have issues.
Thanks for the reply, so yea it's winter now and with led lights both running I'll get max reading of about 24°c and that's from my probe hanging at about plant canopy level.So are your temperatures lower in the grow room? That can definitely have an effect.
The learning curve that I had was with burning when I didn't have sufficient Mg.
24 Celsius is not warm enough, I had to add heat. Not a problem since.Thanks for the reply, so yea it's winter now and with led lights both running I'll get max reading of about 24°c and that's from my probe hanging at about plant canopy level.
I'm thinking maybe leaf surface temperature(lst) will be a bit lower?
I've never had these issues before and I have friends that grow using the same system but with hps and they have never had this problem.
It's fucking messed up, makes your brain go crazy trying to solve something that you don't quite understand.
How did you add heat in the end? Did you use a heater or something?24 Celsius is not warm enough, I had to add heat. Not a problem since.
Hps’s blast a lot of heat.
fce 4800 but i started with a couple fluorescents ...you have to gradually increase especially when starting with fluorsWhat mars hydro light do you have? Do you keep it at one setting or gradually increase it? I didn't find any difference in increasing the distance of the lights.
Cold weather is only starting to set in where I live, so my next grow will probably be under HIDs. Last winter was colder and I needed to add a space heater outside the tents, destroying any energy savings from the LEDs.Thanks for the reply, so yea it's winter now and with led lights both running I'll get max reading of about 24°c and that's from my probe hanging at about plant canopy level.

Would almost make sense to go with hid lights and maybe add an led as suppliment lighting? Either way let us know how you get onCold weather is only starting to set in where I live, so my next grow will probably be under HIDs.

So the only thing I can figure out and you mentioned you haven't cheaked in the past your canopy temps so your plants are too close and temps at canopy are too high and they are cupping so the stomata can't release moister and exchange co2 and oxygen that's where the cupping/drooping. I usto run only hps and took a pause growing I came back 5 years later and it's all about LEDS I understand brother don't give up its just a Learning curve and that's what makes growing so awsome never stop learningSo I don't have a laser thermometer to check leaf temps but they're under hps now and look like they're doing better.
But what you're saying makes sense man with the stomata opening up at higher temps, and I think with my leaf temps being low under led, the plants act like they're being overwatered.
I don't have an oscillating fan going but I do have fresh air coming in down low and exhaust air up top going outside so its quite a nice atmosphere with the air being exchanged and obviously running negative pressure so the air goes out a little bit faster than it comes
Last year I added a tower heater being my first winter with LED’s. This year I replaced my mini split a/c with a/c and heat mini split. I also added a tiled heated floor that is on a digital thermostat.24 Celsius is not warm enough, I had to add heat. Not a problem since.

Post above, hit reply on wrong post.How did you add heat in the end? Did you use a heater or something?
I like this for night time temp control. AmazonSo I don't have a laser thermometer to check leaf temps but they're under hps now and look like they're doing better.
