Brown Tips?

using dwc indoors.
6 of my plants have sprouted through the rockwool and most are looking good. but there are about 4 that dont look like they are growing the 2 pedals that first sprout and look more like little tiny threads popping out and curling up. also some have brown tips. pH levels are good and the water is at a decent temperature but am just wondering if this is some what normal or if i should just scrap the thread looking ones.

i will post pics in this threa in a few min.
if you guys can help that would be great, any inquiry is appreciated

1 pic u can barely see the brown cuz of my cam quality but its there
2 pic shows the thread like plant sprouts
what do?

don't freak out yet. they may still live just give it time. Some times its genetics or sometimes the shell of the seed disturbs the tips.

how close is the light.

no light on them yet. should there be? or wait a bit?

yes they need light just just make sure the light is not to hot

there should be light on either a 24/0, 22/2, 20/4, or 18/6 light schedule

riggd this up for the time being. 24hr sched or 18/16 till lamp comes you think?

yea since that light is very low power/heat i would drop it so that it is almost touching the tops of the plants .. like 1/2-3/4 inch
