i have about 30 seedlings in an ebb an flow at 75F watering with 5.8-6.0 PH distilled water 3x a day 20 minutes each cycle under 2- 250W MH . they are 2-3 inches or maybe a little more. constant fan blowing on them. im a little gunshy about adding nutes (GH 3part) as i burned my first ones and these actually got slightly burned from leftover salts in the hydroton at first. my ppm is now 130 and all looks good finally. should i wait another week or should i ease into it? and if so, do i just add micro and grow 1/8th dose? thanks for the help as i dont want to screw these up. i finally have some healthy plants after a horrific start
