Purple top, brown edge of leaves and a strange bug!
Searched the web to no avail but have four different problems with my tomato plants:
1. Tops of some of the tomato plants are purple. The veins and the leaves and the growth on the top is stunted. Is this due to overfeeding / potassium deficiency?
2. Tops of some to the other tomato plants has brown edges on the leaves that looks like rot? Only appears on moneymaker plants and the useless Jamie Oliver plants I bought from homebase (2 out of 3 are already dead).
3. Black Fly (aphid) infestation for yet another year. Trying nematodes this time. Any advice much appreciated on how to get rid of them.
4. Loads of strange red larvae are in the soil. Can't find out what they are. Possibly moth?
Any advice on these problems is much appreciated.
