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 ?

Thank you Jason for your care & time.
I did not find any critters. But I will have a thorough look and update if anything.
This one was healthy and looks good a month ago. But recently all leaves started becoming yellowish and dropping off. Only 15% of the plant leaves healthy, looking green. It has not produced even a single full ripe tomato yet. All the existing tomatoes are under some kind of bug attack.
Even I faced this issue last year and posted here :
I think there is definitely something wrong with soil or fertilizer. Can anyone please guide me ?
Tomato plants are outside of my field of expertise. But we are lucky to have the wisdom of great gardeners in our community. All advice gratefully received from @Grub80, @Noelle, @timjeffries, @bergs and @robchin who might like to share their thoughts on your tomato plants.
Are you able to describe the bug that's attacking your plant? Or share a photo?
Here's hoping we can get to the bottom of this mystery.
This is a different situation to last year, when the lower leaves were yellowing.
My guess this year is that the soil in the pot is getting very hot during the day and that is affecting the roots. If the roots are unhappy then the top growth and fruits will suffer. If you want to grow tomatoes in pots, make sure they are BIG pots with lots of potting mix in them - the more mix, the greater the mass and the longer it will take to heat up in the sun. The other option is to grow them direct in the soil where the roots will also be much cooler.
I don't think the problem is nutrition or bug related - there is some bug damage but as @robchin said last time, the damage isn't important if the plants are otherwise healthy and you are picking tomatoes.
Bigger pots and placing them where the plants themselves get good light but the pots and potting mix are shaded during the hottest part of the day will probably make a big difference. Tomato plants don't have to be in full sun to do really well - they just need plenty of light.
Also, use a fertiliser with a boosted level of the trace element calcium to help prevent diseases like blossom end rot. In combination with cool roots, plenty of water and bigger pots, I think you will get much better results.
Great assistance as always @Noelle.
@ppp: If you decide to repot your tomatoes, Noelle shared some great advice about how-to here - https://www.workshop.bunnings.com.au/t5/Garden/Re-potting-tomatoes/m-p/57308
