So at 2ml/liter for 3 gal water = 22ml Big Bud. Sounds like alot. But if they are saying 5ml/liter will increase ppm by 300 - then even at 2ml/liter, wouldn't I be upping my existing ppm by 1600 or so? In what way am I being stupid right now?

What bulb would you recommend strictly for flowering? I'm concerned that the hortilux has blue and I don't need that for flower? From what I'm reading the blue is for veg growth and that's the last thing I want. Right? Plus the Hortilux has far less lumens and I would think that's a bad thing. AND... The 600 seems more white than my 430 hortilux. Makes me worry. I'm fine with buying a new 600 bulb if it'll make this nightmare grow end sooner?

I have no idea why these plants are so tall and am concerned I did something wrong. Seriously.... 7+ feet? It's spindly also.
