Just got some 6 week old clones. I planted the whole rock wool cube in my own grow medium which is sunshine mix#4 gave it a good watering with phd water no nutes and got good runoff. I also have a 400 watt mh light about a foot and a half abve it, dosent feel to hot when i put my hands right about the girls. What is the desired distance for the light at this age? My temps are at about 71-75F 30rh. When can i hit these girls with nutes? Again this is my first grow. ANY help is much appreciated.
