Tomatoes grown in greenhouse
My tomatoes started well and fruit is the size normal to the type but after the first two trusses growth iis very spindly and the plant us obviously short of something the leaves are green but with a purplish veining I use comfrey feed which my outdoor tomatoes love and thrive on. The compost I used for my greenhouse tomatoes also caused me problems with some seed growing so I suspect a deficiency but I do not know what. Help me please, I need a lot of tomato es!! GC FAREHAM

A soil test can be done on your soil mix to determine what you may need to amend your soil with.
This could be a phosphorous deficiency.
