Seedlings wilting ! Please Help

Hello there,

I'm growing some tomato's and peppers for the second year in a row, however this year I have suddenly run into a bit of trouble with some of the tomato seedlings. Practically over night several of them have wilted and are looking very poorly.

They were planted on 8th march into a 12 cell self-watering propagation pots. They are being grown on a sunny windowsill in a London flat.

All has been fine till about 4 days ago when I noticed a rotten egg smell coming from the water reservoir and after inspecting I found about 6 small white mushrooms growing on the capalery matting and some clear gooey substance in the water leading up to the pots base. The seedlings looked fine so I changed the water, washed the matting and put them back.

Yesterday I notice 3 seedlings of the same tomato type had wilted a bit and I could smell the rotten smell a bit again. I repotted the wilting 3 seedlings to try and save them this morning as they looked even worse but they don't look good. When I was repotting the roots of the play itself didn't small rotten.

By this evening I noticed 2 more had wilted now as well!

A quick good search said it might be root rot as the soil was to wet and not aerated enough.

Even if some other seedlings are not grow enough should I re-pot everything ASAP? By the photos and description does that sound right?

Ok I will repot the infected plants to see but yes I don't think they will recover. Hopefully the others can last till tomorrow when some worm casting fertiliser arrives, the should I just repot everything even if they could grow more in the prop pots there in?

Interesting why this has happened when I have used these self watering pots a few times before with no issue. Maybe I needed more perlite for more drainage as the perlite I used was the remains of last years and it was quite fine and broken up.

Did those mushrooms have anything to do with it? I have used a peat free compost this year. But I guess the mushrooms grew as they had the right most/wet conditions.

The stems and under the leaves are quite purple as well which a google search says it might be because they need feeding. Could this be the compost not having enough or should I of mixed a bit of nutrients in at the start of germination?

Also, it's only happened on the Garterperle tomato's or is that probably just coincidence?

Thanks for the reply

Ok I will give it a try and hope for the best.

Thanks for the help Jay
