Nute Burn Issue DWC/cab/SCROG/CFL/VEG Moms/Headband

im certain this has been covered 1000 times...but i just cant find specific answers soo....

I accidentally totally fried a DWC mother bucket (with three strains in it lol)

one fried first, and the other two are about 2 days behind it.
Headband fried first, Green Cush fried second, and BDream was 3rd...separated by about 2 days each. Dream is just showing signs...headband is devastated. cush looks like headband did 2 days ago.
i have 2 of these buckets, with mixed strains. all cuttings will go into rockwool blocks, and be separate strains. segregation is key... i know that now. sigh...

Well... i burnt the ish out of it .. everything looks burnt/ rusty/dry/black

coulda been a number of things...

my nutrients:

1. nonorganic thrivealive b
2. GH maxigrow
3. H&G roots excelurator
4. neem oil (that luckily is just there in case)

the equip

1. 3.5 gal black bucket
2. 8inch bucket lid basket pot
3. smallest pump from hydro store... home made drip ring (terrible idea with maxigrow,,it cakes.
4. $11 dual airpump with a redbullcan size airstones in each bucket (1stone per)

i hate hate hate the maxigrow..but it was expensive and i cant bring myself to throw it away... i dont like dry nutes anymore.

i guess id like to know what the best situation is. i will be trying to recover the plants, and likely take one more large round of cuttings, and then try to flower whats left. just to get rid of the buckets. i have an aeroponic system thats being fed by these mothers. slowly but surely, i want to evolve away from individual dwc's, i find them too dificult to maintain.

so heres what i did:

1. i locked the buckets in place about 5 days ago...
2. they are closed system buckets, i knew this was a problem, i just didnt have all the parts.
3. when i noticed burn, i pruned the badly damaged leafs, and tapped the bucket.
4. i ran a hose to an external rez.
5. i then began flushing. i sent about 10 gallons quickly through the rockwool/hydroten to the rez i stopped once the water appeared to lose its brown (thrive alive leaves a lotta brown stuff around..)
6. i SHOULD have checked ppm and ph of my first dump, and recoreded every gallon... but i didnt... i will say, that after adding 4gal of 6.0ph water the ph was coming out 4.9. i diluted it pretty well, and ph was still low
7. i credit maxigrow for the ph problem.. it brings SF tap water to 3.5 with very little powder.
8. i think i am releasing more and more maxigrow as i flush... probably making the problem worse... should i just continue to flush until there is no shift at a slightly higher ph... i.e. 6.7ish, until it comes out constant 6.7 (i.e. 50 gallons of ph adjusted water later)
9. Pruning... should i prune? i mean.. the plants are fried.
10. PH... should i try to shift PH out of the optimal nitrogen absorption range?

again... im certain this has been covered...but i couldnt search my exact answer. hopefully, this post could serve the greater community if all posts try to include keywords.

heres some i came up with:
general hydroponics, house and garden, accelerator, root, scrog, lst, hst, nutrient, nitrogen, burn, rust, rusty, spots, spotty, leaf, leave, leaf curl

If this board will let me, i will keep this post current, and will detail optimal circumstance for devastating DWC nute burn.

THANKS!:rastasmoke:

PIX of the carnage

the spots are the bDream
the close up leaf is what it started at... a day later... most of the leaves were black... by the end of today...this is what it looked like

i really dont want to lose the dream. infact... im willing to chop everything out now (cush and headband... if that would save it (i fear it would leave a nasty dead root system)

nooooo...save her! wish i could heal it with my eyes

it got much worse
i think i need meds of some sort. i wish the Soma talk at the MedCanCup about modifying disease was online.

im willing to veg for up to 3 weeks. if i have to rip the whole pot out... id rather do it now. the other DWC is very healthy... i would like to flower it immediatly..just to complete my first grow...

im thinking i need hygrozyme? will be the most reliable ?

should i cut MaxiGrow immediately? I really want to go organic. im 3/4 done with maxigrow... i wanna throw it away and buy top-of-the-line organic. maybe a 3 part organic? i want to focus all of my money in VEG mode.... im thinking no matter what, im going to need 1 week of veg to heal little bumps and bruises on the bdream.

HARSH pruning is starting to look like the only answer..... to die gracefully, or MAYBE some how salvage the roots (that will create a big mess in my bucket!)

im thinking cut it back to 1 node above every V... no leaves. i really dont know what this will do. my hope is that, it could multiply the budsites if i can give it the right organic mix.

medication is pretty cheap in norcal... this makes me wanna just buy like regular people.

I definitely recommend Hygrozyme! I am also on my first grow and ran into the problems you are experiencing. Your girls look like the roots are suffering, and most likely the ph swing from it has also caused lock-out.

Best of luck and happy growing :hippy:

My guess is that you have them in a poor growing enviornment.

What is the temp/humidity in your grow room?

What are you doing for air exchange, ventillation and exhaust?
