I've tried the cheap-o LED lights. They work...sure. But they simply cannot, and do not, give the same bang for the same buck. Best use I've seen is using the ones that claim to be 'Full Spectrum' as a UV/IR supplemental perimter light. As for your plants, Chevyroad, throw the breeder's timeline out the window...they are never correct, whether it be by a week or 4 weeks, they are rarely accurate if you're wanting your plants to produce the most potent buds that their genetics and environment can permit. Your plant's buds still have a lot of perky white hairs...which points towards you having awhile left to go. You should invest in a 30x Microscope from somewhere like amazon...then you can cut out the guess work and harvest based on the color of your trichs. But no, plant is definitely not done.
