Could you please help me with a problem with my tomatoes? They are Beefsteak Italian Mary, Money maker and Burnley Bounty from seed. I have photos taken at 8 am today.
They are not growing well, they have been in the ground for over 2 months and are about 25 cm tall at the moment. I had done the green manure bit before planting with mustard. The soil has plenty of composted stuff in it as well.
The leaves are turning yellow from the base upwards and curling inward.
They have been watered regularly (every 2 days or so) and fed with a 75% of recommended dose of \'Thrive\' once a fortnight.
Is there a solution that you can recommend?
