Beginning root rot or nutrients coloring roots?

[Oblivi0us]

hi I have been doing the recommendation of daily feed until 10-20% run off. The plants are growing nicely but the roots that come out the hole on the bottom of the pot are turning more brown color.
If I poke around a little through the coco the roots not exposed to the light and air and up a little further away from holes are a nice white color. But these darker colored ones on the bottom are worrying me a bit.
The 1st picture you can kind of see the whiter colored roots in upper left.
Is this just nutrient coloring settling to the bottom or am I giving too much water?

those dont look like roots. (bottom photo)

Root tips will brown, and die back when exposed to tons of oxygen. Its not root rot, keep on trucking.

Agreed. Nothing to worry about.

it's called 'Air Pruning", search Air Pots and read the whys and wherefores

You're good! If you pull the plant out of the container, I bet the roots would be encasing that little square cutout. They don't like light or too much oxygen
