After seeing some 'burning' on a few leaves I thought I'd test the TDS levels of the water and make sure that there were no organics. Turns out the levels in the water were above 100 ppm and after test flushing some pots, one pot ended up being around 650 ppm.
I discarded the soil, repotted (peat and sand) what I wanted to keep and cleaned the tray out. I have Drosera, Byblis, Stylidium, and Sarrs seeds/seedlings sitting in the tray. This seems to be a re-occuring cycle and I'd really like to stop it! None of the soil had the 'egg smell' this time from cyano-bacteria which I use to get as well. I let the tray dry before adding more water. Does anyone have experience with this issue? Where are these TDS coming from?!
The only additives I've used is neem oil. Does it eventually break down into organic compounds? Would adding a sulfur based fungicide to the water help keep the organics off the soil due to the H+ ions bonding or would the organics hold there place in the soil?
Just some thoughts, any help is VERY appreciated, thanks for reading.
