Hello, looks like PH Problems. If the newer leafs okay and the symptoms stopped no problem. If there will come more leafes in the middle and lower section like this on the picture i would check PH.

Orange spots on fan leaves
What are these spots due to? I was using pH 6.5 tap water and bud candy 1mL per L for every watering. Just water from now on. Should I worry? 2 weeks left before harvest

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.

Why is my WW seedling browning?
I have a White Widow seedling that is showing brown spots. I am not sure if the LED light was too close, or if it is showing nutrient deficiencies/excesses. pH=5.8, PPM=160 (80ppm in well water).

Cal-Mag and N Deficiency in Flower? Thanks!
I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

What am I looking at?
Redish Brown spots, and slight discoloration. Magnesium deficiency? Calcium? Other? Gave them a splash of Calmag, but was it even necessary? OR, should I have just swapped nutes and wait, then correct if not improved? (It was nute day, that's why I ask!)

VPD related leaf issue? Brown spots, don't think its Cal related. Pls, any help would be appreicated.
Brown spots on leaves, I thought it was Cal related, and tried different doses, with no success. Could it be VPD related? It can and does get very hot and very humid in the 1.5ftx2.5ft closet. Even when running no humidifier (Live in AZ). I've been struggling with this for months

Fertilizer burn or something else?
Hey fam. Plant seemed fine a few days ago besides a mag deficiency. Decided to foliar spray cal mag at half strength a few times. Now there are brown patches and leaves/stems are curling down like they’ve been overwatered.

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Hello fellow experienced growers, is what I see on this leaf, combined with a reddening of leaf and main stems really signs of a CalMag deficency? Or do I have another problem? And is 1 ml CalMag Agent enough to counter it? Dont wanna risk anything so close to the goal...
