Move your light to 22 inches above the canopy, you have a good case of light stress. Happy growing.

This particular plant might be in a hot-spot in your tent. If the lights are powerful and the airflow isn't adequate, there will be points in your grow area that retain heat. This could be the issue.

To much light!!
Try 15-20% less light if your light is Dimmable otherwise put your light 10-20 cm higher

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves.
Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?Leaves. Curl up

Everything seems to be OK except one thing (week 3). I thought using the greenhouses at night made this, but it doesn't. When I check the plants early in the morning, their leaves are slightly curled upwards, just along the edges. As the hours go by the leaves flatten. Any clue?Week 3

CuppingOn the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?Week 4

Heat and light stress?I think this is heat/light stress. The tips of the leaves yellow and point upwards, while some leaves are trying to flip over. Temps get up to ~80 right under the light, and this bud gets greater than 2000 µmol, but she looked like she loved it up until this point4y ago

browning leavesAnybody have any idea on the cause of my leaves getting brown spots and curling at the tips? It's really just on the big mature leaves and leaves near the buds. Any smaller and younger leaves are still fine. Maybe a nutrient issue? Or is it just that its close to harvest time?5y ago

Leaves turning yellow from the bottom upMy older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx
