I have black spots on my tomato leaves and there wilting. they are yellowing as well.?
Question:could all of this be contributed to lack of nitrogen. well unfortunately today i had to miracle grow them. i don't like using the stuff but its all i had for now.
the only other thing i did to them was use coffee grinds mixed with water once, to give them nitrogen and the black spots didn't start happening until after that.
what is going on??
Answers:
This seems to be the work of a fungal problem rather than a lack of nutrition. There are some tomato foods that contain control for tomato wilt and blackspot. Follow label directions and water the plants thoroughly in the early a.m. careful not to wet the foliage. Slow trickle around the root zone is best. Planting in an open area where the air can move freely through the plants is also a good control for fungal problems.
Go to your local garden center and pick up a fungicide--there are ones that say "for tomatoes and other vegetables". The label says do not pick the tomatoes for 5 days after application--but you probably don't have tomatoes yet anyhow. Also works great on roses when they get fungus. You probably have your plants too close together--you must allow them room to expand!
It could just be that you have tomato worms. They are a big fat green worm.
This definitely isn't a nutrition problem and sounds like a disease issue for sure most likely Late Blight. If you look on the under side of the leaves early in the morning as this is the best time to see and where the black spots are there will be a white looking fuzz on the backside of the leaves where the black spots are if it is late blight. If you have been wet for a couple of days this could hit you quick and hard for sure. There are other disease that can cause these symptoms but late blight is the most common cause. You can purchase a fungicide like Manzate or Copper Sulfate to help control the blight as it is an air borne fungal infection that comes in through the air in a rain storm etc.. Once it gets to the point that it sounds like you have it is very difficult to stop for sure and the best thing that would help is for it to get dry weather for a week or two but applying the fingicides will help and make sure you cover the plants well including the underside of the leaves the best you can since the fuzz I mentioned you may see is the fungus reproducing and contains literaly thousnds of spores that will travel to other parts of your tomato plants and potatoes as well if they are in the same garden and close by.
