Day 52 with serious nutrient deficiencies, can they be saved?

[IDontExist]

Growing some Mephisto in coco with dry amendments. Long story short I'm using a dripper to water which doesn't water the whole pot so the plants ran out of food earlier than I expected. Being a first time grower I realized it probably much too late. I gave them a tea made with the dry amendments and top dressed them on Wed, these pictures were taken Saturday 52 days above ground.

Will they still fatten up and produce or are they pretty much done for? Again, first time grower so I don't really know what to expect. These strains are supposed to finish around 70-80 days. I have a journal here with all the information regarding nutes, lights, etc if that is helpful. https://www.autoflower.org/threads/mephisto-and-night-owl-in-living-organic-coco.74214/

Additional info:


Your probably not going to get many responses, you are blending grow styles, therefore I can't recommend soil fixes, nor can I recommend coco fixes. Your going to need help from someone growing in this particular style...

 

[hairyman]

Well they ain't done for, if you have the watering fixed, I would just nurse them home now with gentle feeds

-- what are these "dry amendments"? Stuff to mix into mediums for that so called "water only" thing? .... those usually take time to break down and release gradually, that's the whole point,... as emergency feeds, it's the wrong way to go,... you need right now available nutes!
The plants are under multiple defc.'s now, P and N most glaring,....
Get away from coco next round,.. this is NOT a soil, it's originally intended as an alternative hydro' medium, a soilless type like Promox, Sunshine Mix (these are peat based),.. coco more so than the others, plus it has a lot of do's and don't's for it use (too many to list here, you need to research how coco is properly used, especially it's odd cation exchange capacity properties, CEC).... Coco cannot be treated like a true soil, or it'll be shit-show the whole way... Basically it's a bitchy medium to use unless you fully understand how it works, and what to do to make the most of it's advantages... that does not include simple soil-like grow MO's.....
Not sure what to do here, pending your amendment info,... I see no pH info about anything, not even the water, and that matters a great deal, more so in coco,... In this case, since you're not using nutes as usual, there's no nute solution to test, but in-pot pH is still critical.... You need a soil pH probe, something made to measure in-pot since you're not doing coco the usual way and getting 15-20+% run-off (using synthetic nutes) to test and maintian proper pH and ppm balance in-pot,... avoid the cheap units, skinny probe, they suck! Accurate 8 is a good model, or a more $ "pro" type probe (often wrongly called meters,... meters are for solutions only).....

Sorry for the lack of information guys. I was more just wondering if they were still viable or not, thanks @hairyman for the answer, but I definitely appreciate all the willingness to help. All the info regarding amendments, pH and such are in the very first post of this thread https://www.autoflower.org/threads/mephisto-and-night-owl-in-living-organic-coco.74214/ I copy and pasted the most of the relevant stuff down below as well.

I'm using Dr. Earth 4-6-3 Home Grown Tomato, Vegetable & Herb and Dr. Earth 3-9-4 Flower Girl Bud and Bloom Booster. I pre-amended with a 70%-30% mix, then top dressed at 24 days with 50%-50%. On day 49 I gave them a tea made with the 3-9-4 following directions on the bag and sprinkled the solids on as a top dressing. I was planning on doing another tea day 56.

No problem pal,,,I lost control of the girl in pics, but she came through,, ain't too bad a set of nugs on her , after all that's all they wants to do is flower.

For a new grower you've taken a lot on and ain't done a bad job, get to the end, regroup, apply knowledge learned, go again


Soak up Mr wairas knowledge ,

PH every time you feed or water. Ur leaves look burnt. Just my experience as I had similar looking plants

-- got it,.. sorry for the delay, got side tracked for a bit!

Anyway, Dr. E' does make decent stuff, but again since it's organic the breakdown and release of available forms of the nutes is delayed until the microbes can do their thing,.. This is why inoculants are highly recommended...though this line does have some in them, it's a pretty feeble dose and lacks diversity.... Enzymes, humic-fulvic and Si, maybe kelp too are good things to supplement with....
I'd still look for a PK booster (no N), the P-K numbers are still kinda weak, and more N that comes with larger doses isn't really needed usually,.... Roots Organic HPK is a good one, liquid bat poo blend basically-

I made them another tea using just the Dr. Earth, 30-70 blend, and gave that to them day 56. I was going to start another one today which would go on tomorrow, day 61. My local grow shop carries Roots Organics so I'll add some of their HPK to the brew if they have it.

Does anyone know if doing teas every 5-7 days is a good idea or not? Not sure if I should be doing them more or less.

Pictures were taken day 59, seven days after the first set

I've got another tea brewing now with the Dr. Earth and the Roots Organics HPK. Last bottle on the shelf and cheaper than Amazon so I was pretty happy.
