It is in fact nutrient burn, probably nitrogen. The tell tale sign is the browning of the tips without turning yellow first/around the burned tip.

It's classic nutrient burn 100% Done it before. Looks exactly the same.

my best guess would actually be a potassium deficiency. since the rest of the plant looks healthy. it starts on older leaves and works its way up.

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.

Is this possible nutrient burn?
Sour Kush Day 24 (Coco/perlite) - brown tip appearing on lower fan leaves. I suspect it's nutrient burn. Flushed with 900cc PH neutral water, lot of runoff, PPM was 391 (PPM in 495). Should I cut back on feeding by diluting the nutrient water or by watering less frequently? TY

Leaves turning brown/purple
The leaves on one plant started to turn a little pale, and with brown/purple spots. And on the other plant it starts to turn more yellow, probably Nitrogen deficiency for this one. What do you guys think ?

First, the lower leaves started turning yellow much quicker than usual during flower. I didn't change any Nute levels in my water because I wanted to see how things went. Then we had a few really hot days then this started happening to the leaves. more detail in week 17

So I know I have an excess of nitrogin and that because I put to much nutes in the pre prepared soil. However, before the tips start burning, also on the leaves itself some burnt spots appeared. Could it be light burn? Thanks!

Discoloration on leaves. Why?
I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/bron color along the sides of the 2 bigger leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Something else? Any thoughts?

What is happening to my plants?
I had them in the terrace outdoors. Temperatures sometimes reach 40C. Lately more and more yellow leaves in the ABC have been showing up. In the other normal leafed plants crispy dried and brown leaves are showing. Now the ABC also is showing some dry leaves and yellow as well.
