Yellowing 2nd set, possible nute burn?

  1. Hey guys, I currently have a van kush and a freebie indica growing in a 5 gallon dwc. I will be separating them into there own buckets tomorrow. There almost into there 2nd week since sprouting with a few roots coming through the rockwool. I'm using distilled water (0ppm) so i though that it might be okay to give them a tiny amount of nutes about 1/10 dose, just enough to raise the ppm to about 100. Since then the van kush has become quite droopy, bit of a lime green color with some burn on the tips. The other seems to be standing strong, dark green, leaves pointing up, but growth has seemed to have slowed and the incoming 2nd set is quite yellow.

    I'm not sure if i'm overwatering, underwatering, or getting nute burn. Any Advice? How much/often should I be top feeding? There's is only 1 long root coming from the rockwool so i don't think that they'll get enough water without top feeding..
    I top feed about 2-3 times daily, 5-10 ml each feed
    Ambient and water temps between 70-74
    PH between 5.8-6.2
    Vegging with about 200 watts of cfl about 5-6 inches away

    Any help would be greatly appreciated
  2. no nutrients, seedlings feed off the seed for a while apparently
