Kind of looks like it could be both light stress and calcium issue.

Flush?I have never tied to flush a plant and I seen if the leaves have too much yellow then it is not a good idea. I plan on doing a harvest in 10-14 days and wanted to know if both of my plants should be ok with a flush.

I hate Canoeing Leaves are "canoeing" alot. I can't do anything about the "heat" because it's outside. The plant looks very healthy otherwise, I just wish it didn't have that symptom.

Leaf Troubles: Nutrient Overload or Calcium/Magnesium Deficiency?What’s happening with these leaves? The tips are curling up, and the DLI is below 45. I’m unsure if I’m overfeeding nutrients or if there’s a calcium and magnesium deficiency. What do you think the issue is? Please help me, I need to feed in a few hours.

browning leaves Anybody 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?

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago. Mid last week I started noticing some burn a the tips, so i dialed nutrients back again. By this weekend the tips of the leaves curled further and turned dark. The rest still looks a bit pale, but buds look good.
