Weird copper/dark purple colors on greenhouse plant leaves. Do any of you k ow what type of deficiency/ toxicity/ root problem this can be ? Closest I can think of is Phosphorus deficiency but I cant pinpoint it. Any help from someone who might have experienced this will helpšš»
Hey there, that's not phosphorous, it's pH fluctuations, probably from rain or watering one time. Try measuring the pH of the water, otherwise maybe it was a rainy day and it messed with the pH of the soil. Hope this helps ! š
