I think I'm chasing another problem. The first pic is 500kb and the second is 900kb.

The seedlings are 6 days old.

Water: 6.0pH, zero PPM then added a small amount of Technaflora B-1 (1ml/4 litres= 20ppm).

Light: Sunleaves Vitalume 4', T5, 54watt, Just moved back from 12" to 18" because I was thinking they might be too close. On 24hrs.

Medium: I switched from Rockwool to Oasis cubes last night. It stressed them but saved their life. I LOVE OASIS CUBES.

Air: Excellent air circulation and ventilation.
Temp: Averages 78 degrees Fahrenheit
Humidity: Averages 55%

I consider myself a rookie grower, but I have a strong background in Botany and the sciences. I think the plant is telling me that it is being underwatered (even though I think the moisture level is fine) and that maybe I should add a small % of nutes because it used up a lot of energy trying to survive after the overwatering episode that caused the stress to begin with. But I am very, very hesitant to use anything but my current 20ppm elixir. Could it really be nutrient deficient at only six days old (unless the stress used up its reserves?). I normally add nutes when the cotyledons turn yellow, but that indicator does not work any more. It also seems to be telling me that it has heat stress, even though my temps are solid. One of these is Blueberry and the other is NL x Big Bud. Your help is greatly appreciated!
