That's just old N tox leafs, degradation is all buddy. But to be safe. Check underneath leafs for eggs and of course you'll see webs. Good luck pal

Flecken auf Blatt und Halm oder Helikopter-Mutter
Die 2 Flecken auf dem vorderen Blatt und die dunklen Stellen am Halm beschäftigen mich ein bisschen. Glaubt ihr, die Pflanze hat ein Problem oder mache ich mir mal wieder zu viele Sorgen? VP 10. Steht im 11l BB AllMix und wurde einmal am Anfang der VP mit 3l gewässert.

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.
Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?

Potential bud rot?
My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early? I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.
