my roma tomatoes have got a big brown spot on the very end just as it starts to show colour, what would you say that is ?

Looks like is lacking calcium, normally we put fertilizer but we forget to put calcium, get some dolomite or some rock dust.

Use Epsom salt - a teaspoon in the hole at planting and even sprinkle another on top of the soil a few weeks later.

Blossom end rot by the sounds of it. Buy some Epsom Salts and put in your garden - from supermarkets. Couple of $$ for 1 kg.

Epsom salt is magnesium sulfate and doesn’t address the lack of calcium. For this coming spring you can buy calcium at Bunnings or your nursery but if you add finely crushed eggshells in your soil and let it degrade over the winter months you will not have to buy calcium again. Boiled eggs water and fish bones buried in soil work wonders against blossom end rot.

Growing tomatoes for years now and keep getting small holes like a grub mark as the fruit is rippening and then goes rotten what treatment if any can be used

I had similar problems - I used some spray from Aldi - don't know if that did any good. Then used tomato dust and I also used some yellow sticky fly cardboards. I think that stopped it a bit. Some kind of grub was in mine.

You dont say much about your particular situaion, and I'm no expert. I had a similar issue with a potted Patio Prize but it was before I had whitefly/thrip. While I was watering it was hitting the leaves, and I think I overused tomato dust. The leaves not only curled, but they also went thick and felt waxy. Plant growth stunted and the small amount of fruit were really acidic tasting too (symptom of inefficient leaves). You should be able to rescue this plant by mulching and only watering the ground under the plant. Trim the worst couple of leaves/branches off every 5-7 days, continue as new growth takes hold. Google an appropriate fertiliser, i cant comment on that yet. New growth should take, but of course they then become a rich target for pests, enter my white fly problem as well. Gentle spray with confidor and rehash the sticky paper similar to the previous post. I'm not skilled enough to go chemical free yet.
