I have a qustion for u guys who grow hydro alot.When my plants get about 5-6 weeks the tips of the roots start to turn brown does any of u get this and if so how do u stop it and what causes it i think they may sell some thing u can add to the water but i dont know what.I do now that this means ur roots are unhealthy.
I have included some pics of what im talking about and yes i know they are root bound but this is the first time this has happend and is not why they are discolored.the problem with the discoloration happins all the time and i need to know why my ph is always right.im thinking it is a much more complacated problem than ph or fertilizer salts left in the water.
