m0useanswered grow question a year ago I agree upgrade your lights, and use white light for the pics, there are better options for aorund 100$ out there right now.
SF1000, Mini-sun2 150w, TS1000 all intro lights all better then bluepurple. Also are you sure it is 30w?
Other options could be a PH/EC pen, help track and troubleshot some basic stuff with them tools.
Good Luck!
