34 days ago I moved 5 of my clones from a small flower reservoir to a bigger one. I cleaned everything throughly and mixed advanced nutrients as described. The roots on the plants looked healthy white before the transplant.
Now the water have a nasty odor, and the roots have become somewh brownish with some slime building up.
My new water is tap water, around 6,5 ph (advanced nutrition have the ph perfect tech)
I’m wondering if this happens either because of wrong nutes strength, water temp ((20-21C) or a weak air-pump?
I have measured the PPM to1200, and ph around 6
