Dead leaves

May also be root problems, a bad ph, a too high ppm, overwatering... so exclude these first before supplementing with all NPK.

Looks like NPK deficiency, N from the yellow leaves, P from the red branches and K from the leaves getting crispy, with the brozeish color and dying.

Leaves on one side are dying but don't feel crunchy.Due to slight nutrient burn problems I've given this plant less nutrients than usual.
But last week the leaves on one side of the plant were hanging and dying off.
They don'y feel crunchy and don't break off when you touch them. But they're thin.5y ago

Wrong pH for three weeksI realized I was feeding my plant tap water with a pH of 8-8,5 for a good three weeks. I just flushed my autoflowers, three times the amount of soil with water corrected to 6-6.5. Will that solve this issue I was having (nutes lockout I think)? Did I fix my soil pH by doing this?Leaves. Tips - Die

Weird Sugar Leaf BurningDoes anyone have an idea what happened to my leaves? They are trying up and burning for some reason but only 3 of the 7 that are in the tent. They are all clones from the same mother plant. At first I assumed it was too much light at 1200 ppfd but dropping it didn't help.2y ago

Fan leaf deficiencies during flower. To cut or not to cut?Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?5y ago
