Roots 707 with GH floranova. anyone have experience?

So what say you? I am about to run this set up in a 5x5 tent with a 1000watt MH followed with an HPS, 7 plants. I've read different things about the 707. some say that it has light nutes while other say that it has high levels already. I was pretty much given 2 gallons of grow and 2.5 gallons the bloom.

anyone?????

i do floranova + protekt + calmag in coco.. they love it i buy the bricks, hydrate them then add 50% perlite, mix it super well.. get 20% runoff.

my base ppm water is 60ppm. after calmag my ppm is 400 approximately. then i add flora nova to about 700ppm range.. never had a problem and it works like charm. floranova is the best coco nute ive ever used.
