Good morning all.
I have grown some outdoor tomatoes from seed and have been gradually acclimatising them to the outdoors whilst keeping them indoors overnight. Whilst I am getting close to planting them up in buckets I’m concerned by their colour. They seem to have gone from a healthy green to a pale yellow. I’m wondering whether they are worth saving or if I need to buy some new plants from a garden centre. Appreciate any thoughts.

That happened to my tomatoes this year.  Some of the plants have recovered and are vigorous, some others did not survive.

I think with mine it was due to too long under indoor grow lights and then trying to get them growing suddenly in full daylight. (Your mileage may vary! )

Any photos?

My thoughts are: Have you been feeding them?  Are all the leaves yellow and have they changed at the same time or just the ones at the base? When were they last potted on? Was potting on into a new batch of compost?

If they are standard varieties might be worth getting some from a garden centre as a back up.

Thanks both, I was planning to feed once I had put them out but I have given them a drink of tomato feed and will see if that perks them up.

Maybe a balanced or even a high nitrogen feed if they are young?  I steer clear of tomato feed until  the plants are much bigger and fruiting.  My young plants don't complain about the odd seaweed and urine cocktail!

I try and give all plants I raise a weekly seaweed feed (if I remember) from about 4-6 weeks after sowing until they get planted out. Especially with the recent compost situation I think this is even more important than previously.
