iron deficiency or sun burn?

[Soliyah]

I've been told its both and I'm still curious.
Its really really white.

What is it? And what needs to be done?

What is the medium and why so little of it? No plant that small is going to show iron deficiency. Tell us the EC/PPM of the base water. And the pH of it too.

It basically needs transplant into decent medium. A slightly larger container. Not the final one yet.

I have it in baccto potting soil, this is my second grow and the first time I've used this soil, and I don't know know the purity or ph of the water i haven't gotten another test pen since the first one i got was defective but always used my tap water on my other plant and I haven't had any problems with the water, I have though earlier today transplanted it into a bigger pot, same medium

Likely the pH is really low by looking at the plant.
