Those are really small. They are still in the seedling phase when the should be showing pre-flowers in as little as a week (indicas). Not nearly enough light. Mine are 35 days old and are around 12 inches tall, 10 branches, and main stems about as thick as a pinky. Plants need 8000-1000 lumens in a 5000-5500k spetrum during veg. If your using floros and they are more than 8 inches away from your plants you might as well be using candles. Get a proper light and start from scratch or if you don't have the money drop the floros to an inch away the tops of the plants and cross your fingers. At this point though your odds of getting anything other than a handful of light airy headache inducing buds are pretty low.
