Had you not added those pics a lot of info would have been missing.
What size pots are they 5 gallon?
Flushing may or may not have been a good thing to do. It may have made things worse.
im4satori can give you ideas on how to feed it going forward, because that beast is going to have to be fed to make it to harvest.
That looks like a huge plant for that pot, gonna make it hard getting through the next several weeks.
Good Luck!

ok the additional pics helped a lot

to start, stop fertilizing her, se is very N tox

I think what would help you most is to follow someone journal who has a similar soil and fertilizer

@tpc_mikey is having great success using the same soil and the same fertilizer more or less / likely less...go check out his journal and see how hes using the same ferts ...sparingly

at this point id suggest watering with water only until shes done... no reason not to finish her

next grow you gotta get your feeds right and pot up every few weeks during veg... you adding too much of this and should be using that and its just way too much

I don't have any personal experience using that fertilizer and since its organic (mostly) I cant provide you with a specific way to mix it like a liquid salt fertilizer
for this organic fertilizer you really have to be on your toes and know what your plant is asking for and not the easiest for a new grower

I would recommend you to consider switch to the GH flora grow and floranova
1 part for bloom....1 part for veg

its a complete well rounded fertilizer thatll work great in soil by itself with nothing else needed and a proper dose is 6 to 8mls per gallon ... this stuff even has the kelp and fulvic acid and amino acids built into it .. its truly an all in one

the soil your using is a good soil, it contains all that's required for many weeks of growth without the need for fertilizer provided the pot is size properly

that plant should be in a 20 gallon pot
organic grows usually need a bigger pot using a soluble fertilizer would allow for a slightly smaller pot

if you want to start a journal yourself id be happy to follow your journal for your next run

Well you had me till you suggested a 20 gal pot,

According to 'Growing Elite Marijuana'

The pot size that works best in soil are large 3-4 gal pots, a 4ft plant will be very happy in a 4 gal pot
(this girl is 4ft)
When growing for each foot of growth, 3/4 foot of medium is needed

ex:
2 ft plant=1.5 gal pot
5ft plant= 3.5 gal pot
10 ft plant= 7.5 gal pot

I have normally grown in #3 pots for the last 6 years, The I have been a member since 2011 using the same rig and nutes
(sucessfully)

Thank you for your input on N toxicity, wasnt sure as nothing matched in the various 'problem' guides. I have been growing this strain all year and this is the 2nd I've had issues with. I am getting to the bottom of the nute bottles and am thinking that ratios are no longer correct

Curious. Have you successfully harvested top shelf crystal in the past with plants that size in 5 gallon pots?

HDPursuit · Jul 27, 2017

I have had some very dank and sugary grows, including some autos.

I have never seen a 20 gal pot at any Grow Supply Store and considering all my girls are limited to a 4-5 height due to grow room restrictions. I have scrogged in #3 pots that were 6-7 oz a plant. I have dialed back since then. I realize that the #2's were small, but last time I had problems it was a #3.

To me 5 seems to small, 20 may be bigger than needed but the plant would surely been happier in 20, maybe 10 to 15 is enough. To me it looked like a plant monster from Lost in space, I expect it to move. I grow smaller plants in 3 gallon pots. I have used 5 but not for a couple of grows. From what I have seen in your type situation following threads and such. Most plants in your situation will definitely get there and have some good crystal but I don't think you are going to get it back to a healthy plant, harvest may also take longer than normal, it's full expression and flavors are likely going to be dulled. Hope I'm wrong. Would love to see dank xtal in a few weeks.

HDPursuit · Jul 27, 2017

I agree that she's not going to be a healthy girl by the time she's done, the Afghani cow grows massive arms. Was at my minds end trying to figure this one out and get her to go another 21 days.
Wondering why 1 plant is affected and not the other??

LOL Plant Monster from Lost in Space

SO you think more dirt for roots and less plant??

im4satori · Jul 27, 2017

my post was a bit long, maybe you missed it so I will say it again

sizing pots for organic grows is different than for soluble fertilizer

you might get by with a ten gallon pot using soluble fertilizer but a 15 gallon would be better

if your going to go organic Id use a 20 gallon...

remember yield is directly related to root mass

in that little pot that plant will yield half whats its potential is

the bud might still be good if its grown right but the yields will suffer and the plant more difficult to care for

im4satori · Jul 27, 2017

how often are you watering that pot?

every day?

Just FYI. The fox farm trio is a mostly salt based fert. Only the big bloom is organic fertilizer.

I grow 4-6 oz dry nug plants perpetually in #3 nursery pots. They are actually 2.5 gallons approx. in volume.

But it does make it more difficult to keep up with bigger plants needs and sometimes leaching the salt buildup more often is necessary.

oh I didn't realize that, my mistake

I thought it was mostly organic

MichiganMedGrower · Jul 27, 2017

#3 go pro nursery pots. Ocean forest with added large perlite for more drainage. I have used salt and organic/ natural fertilizer with same results.

This OG Kush x Trainwreck has been started on pure Blend Pro.

6 weeks veg. Transplanted up from 16oz plastic cup to #1 to #3 pots for tight full rootball.

I don't think it's the pot size in a hybrid Grow.

I think she had too much fertilizer and the room was too hot so she transpired more and burned.

Stop feeding that thing anything. Classic over fertilization. That soil is toxic. Fox Farm Happy Frog already has a bunch of stuff in it already and while I know nothing specific about using Fox Nutes Big Bloom, Grow Big and Tiger Bloom on Fox Farm schedule, I can say with confidence that your feeding your plant too much. Straight water for awhile is all you can do. Yield and quality has already been affected and can't be reversed. Sorry for the bad news.

Thanks, about what I figured

That depends, see I agree with MMD. I feel confident I could grow that plant in a 5 gallon pot and have excellent results as he would. I have grown some pretty big plants in 3 gallon. The problem is you messed up as you already know with the ferts. Now your soil and your roots are not as likely to be as healthy as ours would be so there is a difference IMO.
I see your plant like a car that has 8 cylinders, it's running on 6 right now. each week you will lose a cylinder, but you will eventually cross the finish line. We strive to cross with 8 cylinders but probably loose a cylinder or two along the way.

im4satori · Jul 27, 2017

I don't see why youd want to grow a plant that size and flower it in such a small container when a 10 gallon container would be superior ...its not like a 10 gallon smart pot is heavy or take up to much space

not saying it cant be done but not sure why youd want to work more for it

6 weeks veg my 5 gallon pots are solid masses of root

Im veggin 8 weeks organic

I put them in the 20 gallon pots 2 weeks before 12/12 by the time im done the roots are growing thru the smart pots on all sides..and they require water every 2nd or 3rd day

just not sure why you want to restrict it
especially knowing a plant grows wider if it has a wider pot and root mass is related to yield in soil

I stand behind everything I said except my getting confused over the fertilizer derived from info....

but to each there own
