Roots turning brown
I am doing my first experiments with hydroponics.. So far so good, all of my plants have sprouted and are looking very good (on about day 23)..
My concern is this..
I did a nutrient change yesterday.. I switched out the old water with new water and the same levels of nutrients that the plants were at, except, today some of roots on my basil and on my dill have started to turn brown!! I am wondering if anyone has any idea what is going on?
The plants all still look quite good and have grown since yesterday.. There is also a tomato plant which has had no change in its roots..
