I had 10 clippings taken from 2 different plants given to me for my first grow. it has been 4 weeks and only 1 out of 10 is growing steadily. growing in a 5x5 tent and using a 600 watt HPS. temp maintained at 80 degrees and humidity at 50% 4 out of the 10 have 1-2 roots but no solid growth. 1 looks great and healthy the other 9 not looking good. any feedback would be appreciated.
