Help New Sprouts Seem brown

hi guys,

im very new to all this so if you can help that would be great.

im germinating in rock-wool i soaked them in the correct nuts for 24 hrs, i then placed the seeds in the rockwool i placed them in a heated propagator,the rock wool is moist and i spray twice a day.

i have attached a picture and it looks like the tops of the planets are going brown, the only thing i can think of is i sprayed them with tap water, or the light are to close.

ANY Ideas, and what do you think is the best method to germinate when using a hydro grow.

thanks
J

get some better pics. for a better reply

will do, yeah sorry not a good pic, but do you think it could be over watering as the leaves are turning down ?

They are very young to be that wet...you have to consider transpiration rate of such a small plant...spray them when necessary only...over-care will surely kill them...remove the dome and let them breath

they look good.. relax

how they look today
