Help please! I have some very healthy tomato, aubergines, cucumbers and gherkins plants in close proximity to these cucumbers. I feed once a week with seaweed. ???

I always worry about this because I smoke, but I haven't ever had it. I don't think you have either
You have fungi growing in your paper pots. That can't be a good sign. What's that from? Old compost? Overfeeding? Too acid? Too wet? I don't know, but I get it with compost used too many times
