I am in the UK, midlands. Have these seedlings in a greenhouse and they were doing quite well. Almost getting ready to stick them in the ground for winter.
Almost overnight they have died. Can anyone note what the problem could be?
To much water? Not enough?
Temperature has been reasonable in the greenhouse, 16'C overnight. Warm days it can get up in the 30's but I open it up when its sunny to avoid it getting to hot.
I have been using a general feed for veg once a week. There is also a lot of slugs :/
Some pics, one thing that is strange is that it only seems to be the Brassicaceae family that is affected. The carrots in the second pic are still fine.
The third image is the same plants as the second image a couple days before.
