Top fed DWC hydro.
A few days ago, about a week and a half after germination, I noticed leaves starting to very slightly yellow at the top in the center, so I drained the reservoir (not completely, but as well as my battery operated pump would do, and added nutrients. (General hydroponics trio at 1/2 of the seedling amount listed on the bottles). I also added hydroguard at the recommended amount, 2ml/gal
The yellowing went away but one started to look a tiny bit droopy so I took a look at the roots and it looks like I've got root rot! 😢
Unfortunately I didn't look at the roots when I changed the water, so I don't know if this started before or after feeding.
Does this need immediate action? Do I need to completely drain the water and sterilize the reservoir somehow before replacing it? Is there anything else I can or should do? Cut out the brown? (Which is most of the taproot on one, but it's also got new clean white growth elsewhere)
I should have looked at the roots when i saw the yellowing, but i was expecting to have to feed soon anyway, and in the diagnosis pages the types of yellowing that looked most like mine were all nutrient deficiencies.
FWIW I'm as sure as i can be that light isn't getting into the reservoir.
