HpLVd

I'm not seeing anything that would set it apart from the others to much, Phenotypes perform differently, brothers and sisters can have a wide variance sometimes. This is alittle bit from a quick google on the virus. I don't see this. In susceptible cultivars HLVd induces symptoms (Figure 2) such as shorter internodal spacing, smaller leaves, stunting, malformation (outwardly horizontal plant structure), chlorosis, brittle stems, reduced vigor, lower water intake, reduced flower mass and trichomes I think the plants are looking healthy and you don't need to worry about them. One thing to note is when taking pics for diagnosis, its best to turn off the grow lights if they are not a white light and use sunlight or some other form of light that is not coloured. Your HID lights are giving a strong yellow/green tint to the pics and making it look like a old magazine photo. Best Of Luck!
