root tips turning brown

i noticed some of my root tips seem to b turning brown and looks like drying up but i have them in a drip hydro tub and there 10 days old some have roots that touch almost the bottom of the tote with some turning brown plants look fine thanx in advance

Sounds like overfertilization... whats your EC?

i have no meter to tell ,
could it have been caused by sodium in the water ?

Could do. Hydro isnt for ammatures.

if the roots are being exposed to light they will die off,

its not for amateurs but its not that hard and ive had succesful crops b4 but certainly i dont know it all ive had an ongoing problem with "burnt tips" or dried up roots and was wondering if it was normal for some smaller roots to some times do that like i said others are nearly a foot long and there only around 10 days
