Root rot + Southern AG, recovering? and nitrogen deficiency

[fragileassassin]

@rkymtnman THank you so much for recommending souther ag, i got the idea from him and it worked out perfectly. I did exactly that, took a cup and poured the water over the top of each plant to get the SAG all over the growing media.
Once again thanks rkymtman

I believe I started using it after his recommendation as well.

the only thing i would do is cut down the EC a bit while they recover.

@Darknes01 i've used Lucas too. instead of the 8/16, i'd drop it to maybe 4/8 or 5/10 as the roots recover. then go back to 8/16

In my rdwc I use Lucss at 4mL / 8mL entire cycle. I get tip burn if I go higher.

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.

Ca Hypochlorite (pool shock) works cheap and effective, but I always ran an aseptic reservoir

 

[rkymtnman]

So what do you use now days? There are so many Fin different types of food that makes a person wonder? are they all just the same shit re-wrapped in different containers lol?

maxibloom. dry version of lucas. although the last grow i used maxigro/maxibloom to come up with a 3-1-4 NPK. a bit different than the 1-1-2 of Lucas.

yeah, the highest i could only go a few times was 5/10. i'd go 1/2 then 2/4 then 4/8 and then back to 2/4 at the end of bloom

right now i got a grow tent with 8 of them inside using full lucas 8/16 + 2ml per gallon of CaliMag and not a single sign of tip burn. just trying to say that it might be your lights are too close maybe? My lights are right now about 6 to 10 inches from the top canopy and still no issues.

 

[Darknes01]

By the way guys, should i be trimming this down more? i did some trimming from the top and bottom for the front row and left the back row as is to ask here 1st before i continue. I have no idea what to do in this department lol.

i went from sterile dutchmaster zone to HTH and now to southern ag bennies. each way worked for me. each way is pretty cheap for a closet grower. each way is pretty easy. i think everybody doing hydro should try both (bennies v sterile) at some point and see what they prefer.

what dosage do you do per gallon? and are all pool shock's same? I might try this out on another grow and dont want to buy the wrong one or give the wrong dose and deep fry my plants lol

 

[rkymtnman]

61% cal hypo HTH is 0.10 g per 10 gallon is 1ppm free chlorine. 1 to 5 ppm is safe

I will jot this down and test it out.

Idk, i like the if it aint broke dont fix it approach and am extremely happy with what ive seen with the SA.
Sterilizing just doesnt really seem like an ideal situation to me. It works, but id rather not nuke all the good stuff too.

Let me add to this. I have done a few grows with dwc and always gone the sterli method but have never seen roots as white as i did yesterday with AG. so maybe having bennies vs sterli is better or the overall plant health?

Thats always been my "common sense" feeling about the choice. Its gotta be better for the plants to not kill the good stuff.

whatever you think is better is better.

My lights are actually about 40 inches away from plants. My qb288s are overdriven with a 2800mA driver so I prefer to keep them further away for better coverage. 4 qb288s with blue rapidled starboards for supplement in veg, and I built a 630nm / 660nm rapidled rail for supplement in flower, alongside hlg3 boards 730nm for emerson / eod.

honestly its my 1st indoor grow and i had the lights at 12" from the plant at about 600watts and they started to curl up and get tip burns, i lowered the leds down to like 20% 180ish watts and everything went to normal then gradually i increased the brightness and now in 1st week of veg im at 80% brightness aka 550watts and they seem to be loving it( im about 6 to 10" from canopy) so its a trial and error kinda thing.

Southern AG has one bacteria. ONE. It works, as evidenced by many successful grows on here. So does chlorine. UC Roots is hypochlorus acid which is half of what you get when you add pool shock to water, PH dependent of course. Anyway..
Besides the BA that southern AG has, look up things like Trichoderma fungi which are also sold under the same category as HG, SAG, ect. I feel these, combined with the other bacteria such as BA, can be the real answer in preventing bad bacteria from taking a foothold in your res while using bennies.

Any brand names or particular products you use/recommend? always open to more options, the SA isnt bullet proof, it has its limits like you said.

"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.
