Tomato Leaf Issues


I’m growing some bush tomatoes outdoors in pots which are being watered well and fed with liquid seaweed at regular intervals. The plants are in reasonable sized pots and raised up off the ground. The weather has been quite mild if not very sunny but it has rained every few days in the past fortnight that they have been left outside. The leaves on the plants are starting to discolor ( see attached pics) and I’m not sure what’s causing it, whether it’s viral or some sort of mineral or nutrient deficiency, and whether I can treat it or not. Any help or advice would be greatly appreciated. Thanks.

The soil/compost they're growing in should have enough nutrients to keep them going. Each time they're potted on, they have fresh compost, and that keep sthem going until they're put in their final position or pot. They don't need the amount of food and water that most people think they do

As Fg says above, no feeding is needed until the first truss begins to set for the reasons she gives.
Seaweed extract is good stuff and comprises mostly trace minerals vital for plant health. It also contains some Nitrogen.
I give most of my veg diluted sw extract every 10-14 days from a couple of weeks after germination onward, either as a foliar spray or root drench.
But if you over feed with it, it can cause problems
Most likely it's the weather that's the main cause, tomatoes don't like temps below 13c and they don't like to be rained on a lot - and we've had a lot of both recently!
If/when it warms up, I think they'll be fine

Knowledge is knowing that a tomato is a fruit.
Wisdom is not putting it in a fruit salad.
We really can't grow them outside here - the overnight temps are too low, and as fluctuating temps are also an issue for toms, it means you have greater control under cover for getting that consistency.
It's often a case of recognising your own climate/conditions, and working with that.

After exceptional rain, you may have more need to replace nutrients than in normal conditions. I'd add some general purpose feed as soon as possible and see how quickly they improve over the next few days.
Otherwise agree that warmer weather and less rain will also improve things.
