My seedlings keep turning yellow , they are under a 600 watt HPS on 50%. I stopped watering them as much only water them when the soil very dry. This is my first grow please help. http://tinypic.com/r/169mfeq/8 http://tinypic.com/r/2yy4dbk/8
Are you feeding them nutes? Are you using Tap water? I had that same issue with Tap water. What kind of soil are you using?
600w hps is too much light, even at 50%, they've got what looks like light burn! May be nute burn but i seriously doubt it. Stick them by a window or under a cfl or t-5/8 til theyre larger. ~ poke
Do you think they all gunna die ? Anything i can do to help them ? I noticed almost all of them are growing new leaves. My sout diesel doesnt show no sign of nute burn so thats good .
How close is that light? You'd wanna have it VERY far above those ladies at that young, even at 50%... Also, that soil looks pretty nutrient loaded to me. Maybe transplant into a lighter soil in like a 1/2 to 1 gallon bucket a few days after you give them a good flushing... You can still save 'em, you just gotta be quick and careful.
Too much light and ferts. start over they're only a week max from topsoil, and its gonna get harder starting week 1 with big time issues
