First Grow-18 days, leaves yellowing

  1. Whats good Grasscity,

    So I've been germing a collection of bagseeds I've accumulated over the past couple years and this has been the most prosperous of the bunch.

    She's 18 days old from taproot sprout, so I've got a ways to go. You'll see in the pictures that the older true leaves have begun to yellow...I'm assuming this is due to a nutrient deficiency?

    I used an organic soil mix with some verm. to retain moisture, and water with distilled water (not sure if thats bad or not) until soil is just moist. Shes on an 18/6 routine with 100w of cfls.

    Is there an affordable way to test/add nutrients, and if so, what do you all think I should be trying?

    Any feedback at all would be sweet, thanks in advance.
