Plants deteriorating rapidly, pls help
Plants not looking good! Help! White tips at the end. Brown patches. Leaves curling. I've been feeding it 0.5L Advanced Nutrients Coco Big Buds. The light was fairly close, at 30cm. I've raised the lights to 60cm. It was also very humid, so I've opened the air vents .

Yellowing of top fan leaves
What is causing yellowing of the top fan leaves? Started to happen to a plant that I broke by accident during LST. However around the same time I upped to 2ml/l and moved the light a little closer. My ph has also been high (fine now). No idea which one could be the culprit

Spots on leaves and little twisted...
Spots started slowly showing when it had a different 600w light, too much heat back then, this started a little "save operation" changed light, made the plants look a bit healthier but now it looks like the spots have spread and also affected the leaves above... Are they healthy?

Hey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

Nutrient burn?
Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?
