Now I am confused. My first grow was with two 43 watt 2700k lights per pot in MG soil. They did ok but not alot of production. My second grow I used just one 43 watt 2700k per pot and they seemed burned. I worked on ph and nutrients, but still don't understand how all that works either. The only dif in the two grows besides the light was that I just noticed the second grow was 6 month MG and the first was 3 month. Today starting again, gonna use the 3 month MG. My lights seem to be opposite from what noobgrowr said though. I have 26 watt 6500k bulbs and 43 watt 2700k bulbs, whats the difference and whats best anyone?
