Not light stress, but the beginning of magnesium deficiency.
Giving cal/mag will solve this and prevent it from getting too much worse.

Nute Burn? Or something else?I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciatedLeaves. Curl up

Lighting SwitchingI asked this question on my other diary which is a different strain but part of the same 1st Grow. I may have been confusing with my words. My question is this. My seeds have been sprouted 8 days now running on a 24hr lighting, is it too late to switch to a 20/4hrs ?And Should I?Week 1

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.3y ago

Dry spots on sugar leaves, plant late in flowering, also spotted on another one in the same reservoirHi guys,
my plant is around 2-3 week before harvest.
What is the cause of the these dry spots on some of the smallest sugar leaves on my plant?
The ppm might be too much and is around 1200-1300ppm.
PH is 6.0-6.1
I've spotted it on one other plant in the same reservoir.
Thank you4y ago

Light height full power vs dimmedHi, with light height, does it make a difference to the plant if I'm at full brightness and further away vs dimmed and closer? I'm going to start running out of tent space soon so I'm expecting I'll need to dim in late flower. I think it's ok just looking for assurance :)Week 6
