I have the impression that the Veg LEDs we're maybe a bit much, so I dialed them back by turning off the Bloom Switches. I intially left them on because 204 watts didn't seem like much coming from 400w MH, and I lose about 35 watts each when I turn Bloom off. I'll be monitoring for stretch. I have noticed new growth was often reddish/purplish when it intially emerged. I was adding fair amounts of Mag. If I dial these back and that diminishes, I'll know the light was too intense. I have not found the optimum conditions yet, but I have always maintained tight internode spacing and decent growth rates.
