I have had problems with my growing this year, everything just stood still. My leeks are not much bulkier than a hair pulled out of my head, They are nowhere near to planting stage and as I sowed them – I think – in April, I don’t think they will do much good if I did. I am convinced that it was the compost that I bought, and I am assuming weed killer or some such.
Then I sowed a second batch of ppeas and I sowed them into biggish pots. The few that did germinate looked very much to me as though they had glyphosate weed killer, pale to cream leaves and obvious to me. I have used Roundup before and thats what it looks like to me.
Your tomatoes don’t look bad to me, but difficult to see them properly on my tablet. Have you tried unrolling one of the leaves? I wondering if there might be an insect inside there trying to make a home for itself maybe?
I haven’t grown tomatoes for a very long time, but I am sure that I have had a similar thing with my tomatoes in years gone by ( haven’t grown any vegetables or tomatoes here since 2014/2015. I do know that mine were ok in the end. So there must be someone else who will be able to help you with this conundrum, and I wish you a happy ending .
