Brown plants should i be worried

[Thomas Douch]

Had these planted about 2 weeks now and the edges are starting to go brown had water tested everything was fine. Any help would be great

Those plant's look to be Amazon Sword's. The plant's are actually transforming into their submerged form.

The plant's are actually grow semi aquatic in the farm's. So when you fully submerge the plant they have to transform. If your lighting is adequate your plant will look like this in another few week's.
