I water with 50% distilled and 50% rain OR 50% distilled and 50% tap. I have fed once with Grow Big and it happened right after. Might have rubbed nozzle on the underside of the leaves. I water every 2-3 days and water until drop of runoff appears in tray. How much runoff?

Many or low nutrients?Hello Growers What could it be? I thought it would be a nutrient deficiency (EC-1.0) so I picked up the nutrients to EC-1.4, but it's getting worse. Do you think they'd have a lot of nutrients?

Spots on leaves Anyone know what's causing this? Slight discoloration and rust spots, mainly on older leaves. It's not that bad but quite spread out. did spray with neem oil recently, so is it just burn spots or a nutrient problem?

Leaf spots!Leaf septoria or nute deficiency? Don't have ability to monitor pH or ppm. Do I cut the affected leaves off or any other home brew solution? 3 different plants in the photos.
