what's wrong with my baby??

Ok so I'm new to hydro this is my first hydro grow and I'm leaning towards boron deficiency but not sure and would appreciate input.It's just the one plant the rest are thriving but the white label white widow one seed wouldn't germ and this plant is the one that did germ.View attachment 3340200View attachment 3340201 View attachment 3340200 View attachment 3340201 View attachment 3340200 View attachment 3340201

As long as the plant has those little round leaves, cotyledons, there's no such thing as a deficiency. Check your res temps, roots for rot, light leaks, ph etc. Its not a deficiency.

What are you using to feed them and at what ppm/tds?
