Yellowing leaves, brown patches and black spots on my tomato?

Hi everyone! I've never grown tomatoes from seed before until this year. I noticed that as my tomatoes matured indoors (i think i left them too long) they began to turn light green. now they have been put outside (about 2 weeks now) and the plants are getting worse. the pictures bellow will explain the problem better than i can. Only one tomato plant (out of 6) seems to be relativity free from these problems. Please can you help me identify the problem and do something about it?

Also, i have given another 6 of my plants away to a friend when they were still small. At first they had similar (but not as severe) symptoms, but those plants are now all healthy. (they did plant their tomatoes out earlier than me though- other than that they treated them the same way). Mine are not getting better, even the new leaves are starting to yellow. Thank you!

even the young leaves are beginning to go bumpy where they are yellow.

What is your potting mix?
Have you fertilized?

Hi! I'm so sorry, Jean001a, I haven't replied sooner but i have been away (got the neighbor to look after the garden :). Thank you for you response. I had used miracle grow organic all purpose plant food NPK: 7-6-7 when i transplanted the plants to their grow bags. (i don't know what it is made up of though). Luckily it seems as though they have recovered. the leaves are mostly green. However, i think that the fertilizer had too much nitrogen as the plants are now 1m tall and are only just starting to set their first trusses of flowers.

The lanky plants are a function of too little light.
