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 point

Tips of leaves turning
The tips of leaves are turning up a bit. I guess they are doing that because of high temperature, but could there be any other reason they are doing this?

Fast-growers starting to show issues.
Got some issues on these fast growers. I've been treating it as a cal-mag deficiency, however I've been feeding calmag for two weeks and its only getting worse it seems. Any thoughts? PH is 6.0-6.3, PPM 444 feed, RH 47-50%, Temp 77-81f.

Yellowing copper leaves late flower
Harvest is coming up soon and I have noticed some of my leaves mostly the bottom but some on top also have started to turn yellow with brown/copper spots. I believe it is cal mag deficiency, will this mess with my yield or quality of the bud?

Hey folks, I just noticed some kind faint yellow dots appearing on a couple of the oldest leaves on the Elixir. Any idea if its something to be concerned about? It's my first grow and I have no idea what it could be. Are they just old? Nutes? Disease? Temp? Humidity?
