RDWC deficiency help.

What deficiency does it look like.
I am on week 3 of veg in my new RDWC I built to alien specifications.
Water is 19 degrees it's 28 degrees in the room ec is 0.8 as I am feeding to the Athena feeding charts.
What deficiency is this and what's the remedy

Not familiar with Athena, but what is your EC, ph, relative humidity?

Are you monitoring your ph? It looks like nutrient lockout.
