Is it sulfur deficiency?

[rootcap]

Hey all,

I got a problem with one of the plants. i'm not sure if this is sulfur deficiency and i need your help.
This baby grow from 10-12 years old seed, and i have no idea if it's male or female. he germinate very good, but when i changed the pot i tryied diffrend kind of soil then i usually use and it came out too muddy after watering it...
the pictures you see is 2 weeks after i switched the pot and i tryied to add some compost and humus (EWC) to the soil, i placed some compost on top of the soil also to give it some air from the top.
Also, 4 days ago i flushed the soil with PH 6.5 water.

I really dont want to lose this baby... Anyone can help ?

Well without knowing anything about the particular soil you are using I would say this:

Classic nute burn which compounds or leads to overwatering problems.

Regardless, plants look like they are rockin' right now and kicking out new growth. I would just go easy on the watering for a little bit, and hold off on the food unless you know they really need it (Pots start drying out too fast).

I thought it was ferts. and i stop with them 2 weeks ago... this baby is 5 weeks old... i didnt water the plant since the flush and i still waiting for it to be almost fully dry.
I'm watering with PH 6.5 because of the thought about the sulfur.

About the soil, i have no idea what it have inside because it got plain white cover. - i can say it looks like medium brown dirt with some coco inside. when i water it, the soil become muddy.

Yeah she's in a good size pot as well, probably compounded to the earlier problems. I think you'll be straight now.

Filling out the form would still be good though as we might see some things that could lead to potential problems, even stuff like lighting & ventilation issues.

Also, you need to get a plan in place for what you are going to use for soil & nutes next time. Are you in a country where it is hard to obtain stuff? Are you trying to go organic?

There are many options, a lot of people use ffof and other soils & nutes (ferts) you typically only find at ass-rape ($$ > MSRP) grow shops. I'm a big fan of pro-mix & sunshine mix types, peat based "soilless" mixes that come only with a starter charge of nutes, but proper amounts of lime & perlite. And feeding them with chem nutes like GH (general hydroponics) Maxibloom or Jacks/peters blossom booster. Your water source effects things as well. There are also some great just add water organic recipes on here.

Thanks man,

you can say now i have a CFL Mini-Grow. 200w CFL's for 3 plants. the grow box heat is going for 27 celcius (around 80F) and i'm working to get it down to 23-24c. 1 intake fan 1 outake fan.
about my soil, usually i used a rich soil-less Peat and coco coir (just learn it now... lol) and right now i started to use the "LC's Soil-less mix #2" from the sticky at the organic section. (Thanks ixnay007... lol) - im just waiting for my pulverized dolomite to arraive. - right now the mix i'm using got no dolomite at all, but for the next grow i'll have a lovly mix...
The plants grows in 2gal Smart-pots.
Also, i'm using Bio-Bizz for food, Bio-heaven, Bio-grow, Bio-Bloom, Root-Juice and Alg-a-mic. it's going like 1 time with ferts (as needed) and 1 time water only PH 6.8

And as far for your question, yes, it's very hard to find all the recommended products where i live... but for now i think i'm good...

Sulphur deficiencies are less common so it might be something else. The plants look good to me so I would wait a while and see what happens. If you do an internet search on "Marijuana Nutrient Deficiencies" in this country it takes you to another seed company web site that has some nice pictures of nutrient deficiencies. It is against the Terms of Use of this web site to talk about other seed companies so I can't name it. Also I don't know if the web site I am talking about shows up in other countries. I think you are going about it right so good luck and have fun growing.

Your soil is rich, dont nute for the first 2-3 weeks besides some root juice, its over watered with nute burn. But the new growth looks good, your flush worked.

Cap,
Leroy's first diagnosis is IMO correct. The droopiness is tell-tale.

You say the soil is too muddy, and without knowing more about it, I'd suggest, if you think you can manage it without killing the plant, you re-pot using a quality well known brand of potting soil, or mix your own. I like Happy Frog.

If you mix it, don't make it hot with nutrient rich ingredients. Maybe 10-20% worm castings or compost and 30% perlite, with the rest peat or rinsed coco. Inoculate at transplanting with a good product like Plant Success Soluble, or Great White, etc.

If you don't repot, inoculate with next watering. Let it dry till plant starts to slightly wilt, then water, then wait 1 day less than it took for them to start to wilt, and water again. Or you can use a moisture meter which takes out the guess work. Good luck. -granger

pretty simple...over watering....and you said you flushed, so you leached all the nutes out the pot...


water less, no need to see any run off, its just a baby, only give it the amount of water it will drink in 2 days max

Over watering ?
i'm waterting the plant once in 3-4 days, when i feel the pot is light in weight and i can see it's dry. but i do wait for the run off, is it bad ?

I starting to belive the soil i used for this baby is really bad. 1st time and last time for this soil ! i can feel it crappy.

The roots are very small at the first 2 weeks, watering untill run off is not a good idea. Give them no more then 100-200ml of water around the plant (use the BioBizz cup), Plus there were no perlite so that makes it even worse..

with soil that does not drain properly, it gets water logged and deprives the roots of oxygen, and leaves the roots sitting in old water that the plant has not absorbed. the fact that the water does not drain properly and gets the soil all muddy like, this is the same as overwatering even though "technically" you are not over watering by watering too frequently, but rather too much water at once...

in your situation an easy fix would be to allow the water to wick up from the bottom, being that the soil gets all muddy and waterlogged leads me to believe that the soil has good wicking properties. so if you water from the bottom till the pot feels properly watered, then remove excess water from the bottome tray/pan or whatever...

the other option is that the plant would have to be dug up and repotted in a smaller container and better drainage(more perlite/sand/hydroton....ect)


last option would be to just water alot less when you do, and dont water till runoff...try and give enough water so you have to water every 2 days at most...your problem will clear up in a week or 2....


dont flush, your plant is already hungry

 

[SativaKeith]

Hey Joe, does one flush clears out all natural nutes in fresh rich soil ? I'm asking because i recently flushed a 3 weeks flowering lady (8 liter pot with 12 liter ph'd water) until all runoff was very light orange in color, and didn't feed her for a week now, should i boost full dose on next watering or start low ? (ps- i has nute lock, run off came out 5.0, runoff after flushing back to 6.7)

well i for the first feeding i personally would give 3/4 strength, then full strength from then on out...

 

[rootcap]

You think it's smart to change the soil now ? i wont hurt the roots ???

and btw. i never waited for the runoff with the smart pots when i thinking about it now.... only with the small containers and when i passed it to the smart pot it had pretty good roots....

 

[Leroy Brown]

I think you'll be good now as long as you hold off on nutes & water very lightly. I've started plants from seed directly in 20 gallon rubbermaids & it can be VERY hard to get it just right, at their beginning stages if the soil wasn't too moist from the get-go I still wouldn't have to water them for the first month!!

As Joe mentioned when the plants are small you can overwater by quantity. Currently everything I start except for autos, seed or clone, is in clear cups inside of styrofoam ones and it's the best move I've ever made, being able to see your rootmass lets you see first hand overwatering (and how detrimental it is.) as well as how to avoid it & when to up-pot. Shit I was even able to confirm that fungus gnat larvea came in a bale of pro-mix I opened an hour before.

 

[rootcap]

thanks guys.

i'll let you know how it's going on...

 

[rootcap]

here some update...
looking MUCH better after the flush, but still got some "mutant like" reaction... the new small leaves looks better but the older ones looks crappy... take a look, ill keep update.
