Can she be saved

[Master_gRoshi]

@Waira
Or whom ever else may have some advice.

Strain
Zamnesia northern lights

Grow
10 gallon basic dwc

Nutes
Gen hydro 3 part flora series
Grow micro bloom

Calimagic. Mammoth p. And great white in beginning..
Typically 10 ml per gallon is what i top her off every day with. I don't have a ppm meter. May be my issue
She drinks about a gal or more a day now.

Temps have been a bit warm in res at around 73.
Ph has been very consistent at 5.7-5.9
Rarely have to add up or down
Room temps are about 82
Rh sucks eggs. Winter has been harsh for the rh. 28%-34% is the average. Even with my small humidifier.


Have tried other brands of cal mag. Was told possibly the bottle was bad.

Been fighting the rusty stuff since veg. She spent most her time praying and getting GIANT so i never worried too much. Just tried making adjustments and defoliated the bad leafs as she grew.

The last few weeks she has really got bad.
Shes already way over breeder time but still has a few good weeks at the least to go.

Is it rust fungus and i have just been fighting the wrong fight?

It has become a very rapid progression now and at the point i cant just take leafs off. It would be 95% of them.
Has now spread to some of the sugar leafs on buds. But not on buds.

Trying to keep this girl from being a total hash plant. Unless this is some sort of fungus that i need to take a flame thrower to?

I should have came here much sooner. But instead i tried to be a hero and fin for my self. Kicking my self for that. The resources are here i just didn't use them

Also. Roots are stained but not unhealthy looking. No slime or rot. Just stained.

I'm not a DWC guy but it looks like a bad cal/mag def.I'll see if someone who knows dwc is around to help you.

thanks nammy
have adjusted levels and even changed the cal mag bottle out. have also considered the possibility she eats cal out of the mix faster than the rest of everything.
im stumped lol.

Hey @Ash-a-Ton calcium in dwc is best absorbed at 6.2 and over. Maybe worth a try making a res at a slightly higher ph.

Have you tried any foliar feeding yet?

I did when she was not in flower and it helped.
And i didn't think to try to fluctuate the res up higher than 6.0

Would forcing the res up and down daily cause a chemical mess with all the acid/base?
I rarely have to actually adjust it. Its pretty much steady. At 5.9 atm.
So how long would i want to bring it up out of the reccomended ph range ?

If you can, just keep the res at 6.2 now. nothing to lose right?
I remember talking with @MedGrower about ph in dwc and he likes to run his ph over 6 the help keep defs at bay

Nothing to lose now. Ill give her a rip. At worst hash plant coming.
So not the rust fungus Then.
Thats good

Yea man whats the worst that can happen.
10 gallon res must be a bitch to switch out

Meh not too bad. But i have found that i dont need to change the whole res very often. And that was also done 2 different times to try to resolve lol. But i could if i had to. But a bit of ph up is 10000X easier lol

:smoking: fellow gellies,....

...Ash, I'm not a good hydro guy, so I'll whistle up @MedGrower too help,... Wow, those are advanced symptoms alright! ... and Ca, IMO,.. it's the way the necrosis kinda follows along the lateral veins... otherwise it looks close to Mn defc. too, that tends to be more scattered and patchy....
... whaaahhhh?? No TDS/EC meter-- ...waaaay naughty Ash! Not that I think this is a nute burn or overall defc. thing, but the uptake info that gives on what you put in, what's there and progressive changes over days can provide clues,.... plus to know your water ppm's! (if applicable)--->
... I figure you're had a good look at the CaliMagic to make sure it's not any kind of cloudy of flocculent? Ditto for your other nutes,... Your water, RO/Di, dechlor'ed tap..?
... was she any kind of mutie, growth aberrations? Sometimes these show odd nute issues starting early on, and they usually don't get better as they mature, worsen when demands increase...
.... the RH% is bad, an exacerbating factor for sure,... it's on the edge zone for the plant to start really shutting down transpiration to preserve water loss, when that happens the nute element highway from roots up pretty much goes parking lot too, which in turn triggers some odd symptoms,....

----- Ca availability over pH in the critical zone is a bitch! It's at a "saddle point" in the optimal zone... Not all these attenuation bar graphs agree perfectly, but the trend I see and what other text recommendations say is 5.8 and few points under is where Ca uptake is best,.. toward 5.8-6.1-ish it gets lousy, then into low 6's it starts to improve again,.. but at that point you're too high pH for hydro in general, so lower is better,...
