Does KelpMax contain Urea?

[ChrisMalaga]

I've been reading this forum for a while and I use self-watering and LECA for my orchids.
I read great things about KelpMax and I consider buying it (it's available on Amazon, here in Spain), but at the same time I'm a bit worried about its urea content.
I buy orchid specific fertilizers that are urea-free, and I wonder if this product contains urea, which could be the case, considering it's an extract of Ecklonia maxima (seaweed) and other similar extracts of the same seaweed show urea in their formula.
Does anyone have any reliable information about this? Thanks!
