Start with what changed
Note when the change appeared and which plants it affects. Record medium, stage, watering, temperature, light changes and the full feeding recipe.
Look beyond the leaf
Similar leaf symptoms have different causes. Check roots and drainage alongside nutrition. If a problem sticks around, use water, media or tissue tests.
