What is my deficency?

[OChydro]

I would like to ask if anyone can identify what deficiency my brussel sprout leaves are displaying?

Genhydro drip water farm
pH 6.0
EC 2.0

Thanks

Sorry for the delay in this post. I simply don't have much experience with growing brussel sprouts, and was hoping others with experiance with them would way in. I just don't like them myself (go figure). I was wondering how they were doing? As I looked up the pH and EC levels both might be a little low.

I grow them in dirt but not hydro.
