If in doubt start low, see how they are. Usual hydro stuff 0.5ec and go from there. I'm week 3 veg on 0.9ec (1.6 total) and it drops slightly every day which is perfect. I'd rather top nutrition up daily than go too hard.
I cannot see how that can happen as the seedlings are not in there long enough as they are ready for transplanting into your main system once good root mass has been achieved.Fogponics doesn't work that great, from what I remember. The nebulizers destroy the nutrients and the salts build up very quickly, causing them not to work. Probably the reason no one really talks about it much.
Got some pics?I have been using a fogponic set up for around 3 years now and have never had any problems and my plants grow quicker. As soon as the seedling emerges it goes into a net pot and then straight into my aeropod with the fogger positioned in the middle and then I fill up the pod with solution until it is around 1 inch above the fogger nozzle. Set the timer for on for 15 mins off for 15 mins using a non digital timer 24/7 and you will get very quick growth rates. A good tip is to make up your solution in a big bucket as it is easier to set the PH level in a large mass of water then transfer what you need into your fogger set up.
