First Indoor Grow (Trainwreck)

Hey eveyone! Im new to this Forum and i'd love to get some Feedback on my current indoor grow op using the strain from Humboldt county, Trainwreck from seeds. Here are some pics of one of my thriving Plants, It's about 4-5weeks old, started them indoor under two 400w fluorescent tube light, now current in veg under two 400w tubes not sure what kind (im a noob) but the light is violet/purple. Currently on a 18/6 light cycle. Any tips? Im plaining on using the florescent light for cloning and seedlings, 400w Metal Halide for Veg, and sodium Pressure lighting for flowering/budding on 12/12 of course for my next grow. Please leave feedback! Im learning as i go
