20-Day Seedlings with Mag Deficiency in FF Light Warrior?

[bigboerboel]

This looks like mag deficiency, right? I thought Fox Farm Light Warrior had enough nutes to make it to the first transplant. Could this be because I'm using RO water? I started the Cal-Mag plus on the last watering, but it's not improving.

Any opinions???

What are you feeding her?

Until today, nothing. I thought they could make it until the first transplant. I received some good advice from the Rollitup guys last night, so this morning I fed them a 2/3 dose of Big Bloom, Big Grow, and Cal-Mag Plus. The weather is improving next week, so they'll go outside in FFOF.
