Absolutely nutrient burn related. I agree with high roller. Water only next few times then dial back on the nutes some.

Strange yellowing leaf in flowering
What's wrong with my plant? New growth is yellow at the base of the leaves. They've been fed more than usual so cutting back on nutes and I've given them plain water today.

Why is One growing perfect the other is struggling
Why is one of them doing so well growing better deep green leaves and the other is at least 2 inch shorter and leaves are yellowish. I’ve been feeding them both the same I’ve missed the shoter one of the soil is still damp. I’m guessing nutrient over load so thinking do a flush

Halb gelb, halb grün
Meine Pflanze zeigt aktuell leichten Kalium Mangel. Aber irgendwie nur auf eine Hälfte der Pflanze. Die andere Hälfte sieht gut gefüttert aus. Kann mir das jemand erklären? Also warum betrifft der Mangel nicht die komplette Pflanze?

Yellowing of leaves Week 9
Help! Is it normal to have such yellowing Week 9? The buds are still green, but the bigger older leaves are quite yellow. Same strain different plant still very very green. Might be the difference between topping an auto and not topping an auto?

Can this stretched seedling be saved?
So, my first seedling spent a few days w/weak light and got stretched. I then started “Shorty”; both outdoors the last three days. I buried “Stretch” 3/4” deeper. Is “Stretch” (the first plant) totally fucked? Anything else to do? 1st pic is Stretch, 2nd pic is Shorty.

Yellow leaf tips and edges
Hi I've got a problem that I've seen from the start of my grow and it's getting worse on older leaves now - zoom in edges and tips are turning yellow. I thought it was magnesium so I've dosed with Calmag but it's not improved - I'm Ph6.5 - any ideas?
