White/brown border on tomato leaves
white/brown border on my lower tomato leaves
I am using a continuous flow system. I have white/brown border on my lower tomato leaves. Is this due to a nutrient problem of some kind?
Answer from Stella:
Tips of leaves are brown is likely nutrient too strong flush with clean water and mix a new batch.
Hot dry air or too close to lamp can also burn.
Hope this helps!
