STOP WATERING THEM. LET THE TOP GET DRY. As long as when you stick your finger down the side, it's wet down 1-3" below, that's what you want. If anything, use a SPRAY BOTTLE to wet the surface if you want that kept wet.Hey guys first hydro grow here. I am growing in coco and using a 600watt marz hydro light. It has been 1 full day sense i planted them. 1 seed is open and the other 3 still didn't open yet so the leaves are not out. I am hand watering 2 times a day with small amounts of water not flooding so there is run offs. I am growing 2 white widow autos and 2 northern lights autos.
Ya I am going to slow down on the watering. My light is like 2 to 2 1/2 feet from the seedlings is that to close you think? I got a fan blowing crossed the light so they are not getting heat from the light
Put the light as close as you can to keep them from stretching.
I'm excited to see how your plants turn out because I'm growing Northern Lights Blue auto at the moment, which your Northern Lights is the parent of. Don't worry, I'm not asking for child support...
