Since I don't see it on any of the other leaves just the very top ones, I have to agree with you on the light burn.

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?
Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening

If you'd please look at the pictures with 'question' stated below them? This is actually the biggest bud, only it is showing these strange edges. There is (for now) no budrot, i checked. The leaves are firmly attached. What should i do, harvest it? The other buds don't show this.

What is this deficiency?
Some leaves are burnt but the ph is good, watering is good light and temp good soil seems good and balanced. The humidity is very low can it be because of humidity?

Help! Why are my leaves turning yellow?
Not sure why some of her leaves are yellowing on the edges. Is this due to environment? - 78.3°F | 64.8%RH Or a watering issue? - Currently she's drinking 8-9 cups a day through a sub-irrigated planter (EarthBox). Or maybe a deficiency? - See Logs for complete details.

Co2/Temps/Nutrients
I pushed the temps up and got the VDP on point w/co2. Now since the plant is drawing a lot more water up through the roots, I've noticed very slight nute burn on the newest leaf growths. Do you have to drop PPM's as temps rise? I thought it was the other way around?

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
Ich habe 2 Pflanzen in Zelt und eine der Pflanze zeigt ziemliche Mängel. Viele Blätter sind mittlerweile gelb mit braunen Flecken. Die andere Pflanze hat diese Mängel aber nicht, beide wurden gleich gegossen, etc. Ich habe vor ein paar Tagen DolomitKalk und Worm Casting benutzt.

Calcium "deficiency" at 8ml/RO gal and still no improvements in weeks.. now my other tent has started the same spots.
Cal excess or Mag problem? My Blueberry and Wedding Cake Autos are now spotting in new and old growth. Even at 8ml/gal CALiMAGic for a couple weeks no improvements. feeding nutes with two days of just calmagic RO water in between with runoff about 0.5 gal daily in FFOF soil
