Plant dying dwc single bucket

Por lo que veo en la foto de su diario tiene pudrición de raíces. El problema está muy avanzado. Su problema puede ser por la falta de oxigenación en la solución nutriva. Existe una baja probabilidad de recuperar su planta cambiando el agua de su cubeta y agregando peróxido de hidrógeno (agua oxigenada) 10ml cada 3lts de agua. El oxígeno mata a las bacterias no deseadas en nuestra solución nutriva. Mucha suerte.

Looks like root issues. Possibly rot. Did the old solution stink, roots slimy? The ph being out of line is not helping either. Only root tips need to be in solution about a inch or 2. I keep my vehging ph at 5.8.

I'm sorry to say, they appear to be distressed. It's possible they experienced significant stress. I had a similar experience a couple of weeks ago when I realized my pH was broken, but unfortunately, I found out too late, and my plants died. You can try adding fresh water with root stimulators because it seems like they haven't been taking in any water. Check the pot to confirm if they're absorbing water, and if they are, there's a chance for recovery. However, if they're not taking in water, it may be a sign that they are beyond saving. 😭🙏

Hey man I'd bet that you have a bad case of nutrient burn. Looks like you nuked the roots. My suggestion is to fill up a new reservoir being extremely easy on the nutrients (250ppm) and making sure pH is good. Let it recover and put out some new growth. You should see new root growth in 1-2 days coming from your net pots and then like 3-5 days start seeing some top recovery. Goodluck!

how it progressed, what you are providing in the water nute-wise.. details help. sounds like some shitty hydro nutes that aren't ph-buffered. pH shouldn't swing like that with any reputable hydro nutrient brand. and, it's not new knowledge.. lol.. it's just that pot brands are often started by half-wit monkeys with no experience in agricultural products.... they know they can make a half-assed product, bloat the price, slap a cartoon on it and hobby growers will be creaming themselves over the nonsense marketing claims.
