Where do you see a listing of the micronutrients in SuperThrive? It's not a micro supplement. It's a hormone, and has a crapload of urea in it as well.
Use a micro supplement for micronutirents. GH makes one for hydroponics.
With all that secondary growth, it actually looks like you'd be okay to flower. Looks like more than 5 nodes to me actually. But get them healthy first.
I am not trying to dis your game, but you are reinventing a perfectly functional wheel. Go pick up the GH 3 part and some calmag and run the way that works. If you cannot afford the $20 USD for a pint each of grow, bloom, micro, and the $15 for a test/up/down pH kit, you should consider growing outdoors, where you can use practically any fertilizer you've got kicking around (not the azalea stuff though). Your electricity costs more than that!
