    Default Dodgy brown spots on my seedlings

    Hi guys I popped in to see my little ones just after the lights turned on and they have developed these really weird brown marks on the leaves. They were absolutely fine yesterday when I checked them so this has happened in the last 24 hours. Any help would be much appreciated Click image for larger version.

    Temps and RH too low during lights out, need a rad mate for lights out IMO. Looks like temp/RH stress to me She will be fine though if you get the environment stable, Ive had it before.

    Temps need to be constant 25 to 28 mate and RH in veg should be over 60 really 30 is far too low. Temp and RH are connected so raise the temps light out and see what humidity does.
