Glad to hear it. I agree with your decision to up the tds like you described. Your plants are thriving and they're taking in the nutes pretty well right now. I wonder if the brighter light also helps them to grow faster, so that they need more food.
Both vegging and blooming lights have been switched on for full spectrum after the first month so the lights haven't changed for awhile so it's not the LEDs. I dunno, it may be the different flowering Dyna-Grow Bloom nutes.
