poorly tomatoes

My tomatoes (sungold) have gone yellow and a bit curly all over. Looking at info I'm guessing I've over watered them and the fluctuating temp being a bit cold at times at night? Are they likely to recover? What can I do if anything or shall I just throw them away? (sob)

 

Cindy, are they in the gh?
Tomatoes hate a fluctuating water supply and fluctuating temperatures.
Does the compost feel wet or dry when you push your finger into it?,
I would try to water consistently adding a very dilute potash feed every other day or so.
I water mine with Epsom salts now n then.....not necessarily for any magnesium deficiency but as a tonic.
The other thing I would do is wet the soil and glass in the gh during the heat of the day to cool it a little
No, don’t give up....or sob ....Cindy

 

You beat me to it @Verdun great advice...may I just add @cindy ..if the weather permits and it's a nice warm sunny day,plenty of ventilation will help too.

 

Hello Verdun. No not in the greenhouse. The soil does feel quite wet and Ive been watering everyday giving them a good soak under the mistaken belief that you cant overwater them. I was trying to avoid split fruit which is what Ive read would happen if I let them dry out or didn't water regularly. Being on the coast we do seem to have had a lot of wind lately ( the weather....not me I hasten to add!!) Is general Tomato food a potash food and if not what should I get. Thank you as ever.

 

Ah, don’t water as much outside Cindy. Think you need check that a bit more
Yes, tomato food is a high potash food
Fingers crossed Cindy

 

Ah so not in the greenhouse so should have all the ventilation they need...I do believe the regular 'Tomorite' feed is high in potash.I'd suggest not keeping them too wet but give them a good feed and watering once a week..a good one.

 

You beat me to it again @Verdun

 

Ha ha lolimac ....used to be 100 metres champion :rasp:

 

Personally I wouldn't feed until things pick up, I'm not sure where on the coast you are, has it been cold, or what they are potted in, they do look starved I must admit, but how long have they been planted in the pots and what are they planted in compost wise?

Watering everyday is a bit OTT for newly planted toms, if that is the case?

The usual response to overwatering is the plant going limp, yours do not look limp.

 

@pete Im on the east sussex coast. They've been in the pots for at LEAST a couple months and in a mix of mostly Innes no.3 and some multi purpose. We've had some random temperatures swinging from well below average to well above average within days and the blowy weather has been a nightmare.

 

Oh I didn't realise they had been potted that long.
I assume they were growing well up until this point.
I don't think temperature variations have been bad enough to cause that.
In that case it could well be starvation.
