This is my 2nd round in this tent, upgraded to dual HLG Sabre bars for this round, went with 4 plants; 2 White Widow, 2 Black Widow. All organic, FF Ocean Forest amended with Earth Dust. Both of the White Widow plants seem happy and well, yet both the Black Widow plants seem weak and unhealthy. One is stunted and I had to prop it up because it was falling over, the other stands up but is incredibly small. All of these were germinated and planted at the same time, you can see how much the Black Widows are struggling comparatively. Growing medium, conditions and watering has been identical for all 4.
