Root rot

Will do on the top feed, great thought!
I was at 3" below net cups, will raise level to 1"
TDS now at 630 (after another 5 gallons plain water) I guess I need the amino acids, does the calimagic work like an amino acid?

snake oil aka bullshit. plants make all the amino acids they need.

calimagic is just a cal/mg. it's a great one: not too much N and a perfect 2:1 ratio of cal to mg

So I have a 25 gal tank. I have changed out 15 gallons using hydroguard and PH to 5.5.
TDS is at 525 cannot seam to get it any lower
Added two more fresh gallons to raise level to 1" below cups. TDS 515

Should I do a water changeout? I can only mix 10 gallons at a time, leave out all neuts, add hydroguard
Watch TDS and add nuets to raise to 400 then re-PH?

being lower would not be the cause of RR

Not all discoloration is root rot. An old trick is to add an air-buffer of a few inches from the bottom of the net pot to the water level once the roots are grown down into the solution. This helps prevents rot because usually it starts within the net pot. But for real, don't think you got rot.

Thanks for the wake up. I studied horticulture at U of Az but have not practiced it in 45 years. Yea old guy here. I need to think and not follow every suggestion as it's rather head spinning. Similar to growing potato's in the desert, give them what they need and leave them alone. I never saw root rot at the net pot level only under water - must be discoloration from the calimagic. And I cut them off! They look terrible this morning. Perhaps time will heal - Thanks again!

Could be nutrient staining. Could be algae growth. Don't understand why you want to keep lowering the tds. If you have root rot or algae life form, low tds won't get rid of it. Plants need the nutrients.

i just assumed you had rot since you said you had rot in post 1. if it's just stain its probably from the micro more than the cal/mg

Are you using tap water? Chlorine kills. I use reverse osmosis water.
cut off whatever is rotted. Remember some products will stain your roots like humic acid. You won't have those pretty white roots anymore but it doesn't mean your plant isn't taking up nutrients and water. If your plants look terrible wouldn't add any products. Rinse out your buckets. PH some plain water and make sure to have plenty of oxygen in the root zone. (at least until you see some improvement) just my 2 cents.

Thank you for everyone's comments, together my plants have taken off!! Amazing growth and totally amazing roots!! Thank You again!

what happened that was special?

i agree. was it rot that you got rid of? or staining and was never a problem?

My first try at DWC bubble, 2nd water change out and I have root rot. Using Hydroguard from beginning. Cleaned everything with HP, was mostly sterile environment. Two pumps and three air stones. Lined tub with black neoprene, using neoprene net cup covers, no light issues I can see. Any ideas? Do I have to start over? Can I cut the root rot off? Can I add more hydroguard over suggested dosages? Should I spray HP on the roots?
Help! Thank you, JimC

I use Hydrogen Peroxide 3% 300 ml every water in 20gal res. Works great.

It wasn’t root rot, just staining from the nutes or additives I reckon. Mine were like that when they were young so I researched and decided it wasn’t root rot ( hard to see in the photo cause of the lights so just trust me). I left them and carried on as usual and look at them now!

In retrospect, I think it was cleared up by a heavier dose of Hydroguard and additional light blockage through the lid, and using black air lines that don't conduct light. Or I have no clue. Anyway here is what they look like now.

Was wondering if anyone can help me with sex ID? I have one plant that has shown "balls" or I hope not. Not flowering yet.

I can’t see the balls?

Is this any better? Or perhaps I am looking too earl?

780ppm is definitely hot for seedlings. My source water is 130ppm and I use roughly 400ppm for the first two weeks before doing a reservoir change and going up to 500-600. Your water temp is great, how much air are you pumping in the reservoir? Make sure you have more than enough
