To much nutrients dude. Water them with only water then start feeding and you will be fixed.

Lowers getting blotchy yellow minor rusty spots? 4th week of flower...P/K issues?
What's making these lowers blotchy yellow with some 'rust' spots? Any ideas? I think it's probably a P/K issue, am I underfeeding? Blumat drip system, Promix HP, Maxibloom @3.5g per gal. Ca/Mg @ 5ml per gallon. pH @5.8-6.2.

Should I worry?
A couple days after flipping to 12/12… I see yellow edges to new leaves. Should I worry? Wait a bit and see? The other plant looks fine and they’re both getting same nutes.

Spots on leaves
I'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue. Still look like PH fluctuation?

Yellow Leaf on mid flowering stage.
Hello everyone, how is growing? I noticed some leaves turning yellow on the last week, I'm not sure if I overfeed them or if it is some kind of reaction because I put a new fun in the grow. Does anyone have the same kind of situation? Because it happened only in one of the plant

Yellowing on lower leaves. Any idea what this is?
Don't think they should be deficient in anything yet, they're in new Ocean Forest soil and only on day 11 of veg, no way they used up what's in the soil yet. More details in my grow diary comment.

Lower leaves yellowing and curling down
Do anyone know what's wrong ? I was thinking they were getting to much light in the tent with my flowering autos... I'm quite sure it's not about watering

Am I overwatering these seedlings? (Coco Coir) Please help, Thank you :)
These seedlings are about 3 weeks old in Coco coir. I PH the water to 5.8-6.2 everytime. I was watering every 1-2 days as the top soil dried out. Have I been overwatering? How much/often should I water them at this stage and should I wait for them to perk up before transplant?

Nitrogen toxicity mid-flower
So I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?

What's wrong with my seedling?
I don't understand why there is something strange in the leaves of this seedling. It happened to me for the first time, even though I was always raised in the same technique. As a fertilizer I just added 0.5 ml to 1 liter of biobizz grow.
