It could just be shock! The plant has gone through stress and may just be reacting to it. Whats the ph and temp of your solution?

Plants take about 3 dayz to recover from shock.

ph is 5.0 roots arent growing at all and there coverd in a white slime not brown
i dont monitor rez temp

PH is a little low, I would increase it to around 5.8 as this will allow the roots proper access to the macro nutrients it will need to overcome the stress, these get locked out if the ph is too high/low, you could also try something like Super Thrive which is vitamin-hormone liquid concentrate this will help your plants overcome stress just add one drop per litre along with your regular feed, they should start to pick up in a few days.

Super thrive would help.But don't over do it.That stuff is strong and can cause deformities and wierd taste if used too often.
