Tic...how did you get a pic of my girlfriend?
I'm with Growdoc...I lost track of which is which, but they all look like they are doing well. The buds should like the PK boost.
skroddumb...Welcome to IC
You are going to need more than 150w if you wait any longer with the sativas..trust me they stretch like crazy tall during the flower stretch, I ran out of headroom. I used 400w HPS. When chosing light, like Tic said, depends on number of plants and space size. Also heat issues, results requirements (think of the Sun as a model to strive for), spectrum. For fluros more cool white bulbs than warm white like 2:1 for veg, flip the ratio for flower. Think about a medium sized HPS for flower. At 150W(and that's relative to how long the tubes are compared to how many plants are effectively using the light) I think the plants might do only so-so during flower especially around 1meter(39") tall or bigger.
