you've got it under how many of what type of fluorescent(s)? how far is it from the top of the plant? did you get the HPS? there looks to be a lot of stretch and sparse growth. looks like it could be a lack of light. not that pH isn't a factor as well.

get a meter or freshwater aquarium test kit.

how old is the plant? what type of soil and what nutes are you using? when was the last feeding?

you might want to fill out the troubleshooting form. it's in my sig. just copy and paste it here.
