What's wrong with my Tomato plants?

[ppp]

I've got couple of young tomato plants from bunnings. Planted in ground around 2 to 3 weeks ago with little fertilizer, blood and bone. Applied seasol once a week so far.

Couple of branches are not greenish, looks yellow and I think some bug attack. 

Melbourne weather is not great in the last week or so, to think about sunny.  Any ideas and suggestions please ?

Big mistake You NEVER FERTILISE new seedlings,maybe about 8-12 weeks old.You seemed to have 1/2 killed them with Too Much Love,& seasol is very strong- maybe dilute it more-- than instructs says😁
