thanks wildfire for the info.
Sorry to hear about your issues, Its still early days though so stay positive.
Remove the worst affected plant/s,
Hit the remaining plants with some Organic Copper Soap/Spay fungicide now and at 7 day intervals and avoid foliar watering/feeding (only water the medium and avoid splashing) and try to get the humidity down in the growing environment.
It also pays to reduce Magnesium and calcium additives and ensure potassium and Nitrogen levels are sufficient to ensure plant resistance.
Either that or cut your losses and remove everything including growing medium (which will have to be heat/bleach treated or disposed of) and sterilise your entire operation (a massive job I know) and then start again, with new seeds.
I hate plant problems ...
