Yeah you can use spinosad or neem oil to control the pests. As far as mold goes, try potassium silicate foliar spray to control the plants you have left. After this run you need to thoroughly disinfect your grow room/house with bleach. I would go as far as keeping the doors and windows shut while spraying out your grow room, while wearing a mask, evacuate the area for 2 or 3 hours and let the bleach off-gas inside the room. Should kill any mold hiding in cracks and crevices, hopefully get rid of all the spores. Use a strong bleach and water solution.
Anything with a decent concentration of spinosad will eliminate the thrips. BH's recommendation is the best but I've used monterrey with great success a lot over the years.
Septoria... Are you sure that's what it is? A copper based fungicide should do the trick for that.
