Question for you guys: what does it mean when otherwise healthy plants canoe the leaves on the upper leaves?

 

[OttawaGreen]

Here is a shot of a younger plant same condition. What causes this? Low humidity? Low temps?

 

[Graytail]

Heat and/or Mag deficiency.

You could top-dress some Epsoms salts, but you're pretty far along - may not matter much.

They look good!

Thanks for the suggestions .
More details:
My temps are 16c-29c ( 61-84 freedom units) RH is 33-40%
Several plants in different pots started doing it at once leading me to believe it was environmental instead of a soil issue.

Yeah, 84 is a bit high for 40% RH. They're hot and dry, which is leading to the Mag-def expression. Raise the RH and lower the day temp and they'll do better. Also, you want to keep the day/night temp spread to 10-15 degrees for best performance. You're at 23. And plants in late bloom usually prefer lower temps and, contrary to what most think, a little less light.

I bet they're just adapting to the hot/dry atmosphere.

 

[OttawaGreen]

Ok running humidifier and lowering temps a little.

Thanks!

I think Graytail is spot on. Your VPD was way out of sweet spot. Yes I am a big proponent of keeping VPD in check.

High temps, low humidity and magnesium demand. The best thing you could do is raise the rH a bit and give a heavy drench, one kind or the other, both have lots of magnesium. Epsom's would be OK, but the drenches are faster.

Yep! 40 is too low....33 is stressful. 55 and they'll sing to you.

I also have Epsom salts here already. How much to add to each 10 gallon pot? Dissolve it in water or top dress?
Doing the drenches too.

A Super Drench will include plenty of mag......try that first.
