I have a very early blueberry and I noticed the ends started to brown a couple of days ago so I moved the light up Incase it was light burn but then I’ve checked today and it’s gone further up the leaf! What could it be? A deficiency? Sent from my iPhone using Grasscity Forum
Deficiencies usually start with yellowing, at least with my experience. Maybe some drops of water got on the leaf while light was on and crisped the leaf, this is the only time I have had brown burns on my plants.
