I went away for a week and the watering system on my tomato plants failed and I returned to plants that can still be salvaged... however, I noticed one plant is COVERED in a bright yellow powder! It can't be pollen although it is the same colour. Is this a mold/mildew??? Is this dangerous? What should I do?
Don't have any idea what it could be, but after 4 days now, how is the plant? Were you able to find out anything?
Parmesan cheese? That's good on tomatoes. Maybe it was some kind of fungal growth or...if you don't find it reading about tomato problems then it might be too unusual for anyone to be likely to say what it could be without seeing it up close.
