Thanks for taking the time to read this man, any bit of advice is appreciatedSounds like you know what your doing, and nothing has changed on your end. So I would investigate the water, fluoride, bleach, who knows what else is in there.
Thanks for the reply man appreciate it.what size pots are those plants in?
Thanks alot for the reply man appreciate it.i would say change your technique, stop doing NFT as it is very easily for the roots to get a root rot disease/highly prone..
it’s not a widely used technique because of that..
nothing you can do as hope that some of yours will survive..
if not than CLEAN!! everything and get a different technique that your comfortable with..
It was 18 hours under 2x mars hydro ts 3000 at 50% but now on 18 hours of light, now using 400w mh.What's your DLI?
Wow I think you might be onto something here because it really does look like transpiration issues. I've only got the 1 mh light right now at 600w to try and get temps and humidity up.Those LED new to you huh?
You have transpiration issues. Way way to cold for LED. Your room is perfect…for a different light source :)
Get a laser thermometer and get LEAF temps way up. LED will need about a 9 degree increase in temps to reach same leaf temps as an HID room according to Blackdog LED. It’s winter too and your ambient temps are 18-25c so 64-77f. Leaf temps are in the dirt. They need to move water to get nutes. Way too cold for LED.
They look like they are over watered and heat stressed at the same time. I don't know how those lights project, so you should figure out the DLI on each light.It was 18 hours under 2x mars hydro ts 3000 at 50% but now on 18 hours of light, now using 400w mh.
I've not done all of the calculations but I've used these lights before no problem.
I'm maybe thinking it could be something to do with vpd and transpiration.
It's like the plants aren't taking up nutrients or water when they're like this and humidity went down to below 40%.
Could this be a cause maybe?
