Hi guys, im attempting a grow Greenhouse Seed Co. Big Bang in a PVC grow tent using an organic, peat free compost, seeds were germinated indoors and gradually adjusted to the variable greenhouse temperature, they currently have their first set of serate leaves, and are now rooting in the greenhouse with approx. 1mm growth within the last 24 hours. I am watering every 2days (depending on heat during the day) using bottled mineral water with a pH of 6.5. Also misting leaves every 12 hours using same water, what are the risks of my seedlings dying at this stage
