Root rot + Southern AG, recovering? and nitrogen deficiency

"Oregonism XL". If you read the label it contains the bacteria both hydroguard and southern AG have, plus the fungi trichoderma harazaium and trichoderma koningii. It takes VERY little to make a tea with it.
You can buy the concentrated fungi separate, in something like "Bioworks".
As much as I hate to say it, Great White has a pretty decent bacteria/fungi package. Have not used that though.

You should be fine with the 10ml once a week or water change tbh. Its pretty potent stuff and youre already in recovery so youre passed the worst of it.
My system is now also 55gal and I do a 10ml shot on a fresh change and a 5ish ml weekly booster if I dont change it.

I was just told by Emil at Southern AG to use 1 teaspoon per gallon or 8 oz per 50 gallon rez, that seems expensive

one thing alot of peeps dont' do is to make sure they get the southern ag way up into the hydroton too. or whatever media they are using. root rot will hide in every nook and cranny. you could either take your nute solutiion in a gallon jug and top feed each bucket really well. or just mix up a strong batch in plain water and do the same thing. get that stuff everywhere.

if the rot is really bad, you could also hit it with sterile for a bit to kill it (peroxide, chlorine) and once it's gone for sure, then go back to southern.
