Help dying plants

Hello,

so having a major issue now, plants turned extremely yellow. I have been battling yellowing issue for some time but now Idont Have iunder control
I’ll try give u an idea.

made a super soil, but can’t be arsed to get into this. I winged it but everything was looking good, topdress everynow and then with worm castings.
Plants were looking mostly ok during veg, had some slight yellowing, so addressed that by giving bio gro veg as a little boost....ye I think that’s wrong with super soil, but felt it needed a quick boost/help.

anyway. Did that and got through veg cycle ok.
Attached some early flower pics for reference.

but by 4 weeks into flower a saw drasticyellowing, tried giving some more bio grow and was also giving small doses of bloom when I flipped. Maybe every other watering.
didn’t really stick to feeding schedule unless plants looked like they needed something.

my ph of water is 6.3-6.5
Can’t test soil.
Using fabric pots 13litre. And water them around 2-2.5 litres every two days.
They feel heavy after watering. And light before.

I don’t ever water too much and I have never had any run off out of the bags.
The soil to touch feels ok.

I’m not really sure what to do.
Think I have around 4/5 weeks remaining.
Pics attached for most recent images around 5weeks into flower.

what can I do?
Is this N deficiency. I tried to give 10ml per 5l of water and didn’t seem to see any difference so didn’t want to over do it by giving more.

I would say, in my opinion. You said you have fabric pots, never over watered AND never had any run off??? You know a little run off is not a bad thing? Furthermore, i might suggest doing this, after you think they have dried out enough, orrrr you might just need to do this now... Not sure sorry..... Personally, i submerge my fabric pots halfway, in 6.1 PH adjusted water every 2 weeks to keep my nutrients and salts flowing outwards. While halfway submerged in water, i then do my trimming if needed and water the top soil with Ph 6.2-6.5 while soaking. You might need to get some water flow through the soil and try hitting the plants with some dimmer light for a day or 2 idk. Soon as each pot is soaked for 5-10 minutes from start, i remove from bath and let dry in a place they can drip extra water out freely for 20-30min. Then back into my grow tent. This is just my method that works for me . cause my soil is more enriched than i thought and my Fox Farm Trio was turning my plants either yellowish or dark green. Regular ph adjusted tap water to 6.2-6.4 for virtually the entirety is what kept my plants going with very little help from added nutrients. But thats my setup

I hear you. Due to the setup I can’t really move them around too much. I have a net.
However do you think I may need to water enought until I see run off.

12/13litre bags. How much water would you give.
I give only 2-max3l most times.

would you be giving more than 5!or 6 in order to get some run off??

Your medium is organic soil (redundant, yes).

If that were mine, I would simply transplant.

Fun fact: when I first did Subcool's SuperSoil, I had plants look just like that. I knew I fucked it up while making it. Sounds like you did the same ; ) Or just used too much?

Could it be sulphur deficiency? Could worm castings quickly fix this, or bio bizz grow or bloom..

can I even transplant so late into flower?

think I didn’t understand your comment correctly when you said redundent.

are you saying there is nothing left in the soil? Therefor redundent. Because that might be the case. But that was why I was giving some bio bizz too tojust get through this

Soil is living organisms, so calling soil organic is redundant. The comment was not worth the confusion, sorry.

I'm not smart enough, experience enough to say what exactly your plants are suffering from.

Please read my signature.

I would test the pH, ppms of the runoff to determine what medium I'd transplant into.

IMO, those buds are ruined. However, most people here don't align with me in regards to quality.

When leaves turn yellow in late flowering, you don't need to worry that something is wrong, as this is entirely normal. It is actually a good sign, as it shows your plants are using up any excess nutrients.

Nitrogen is a mobile nutrient, which means it can move throughout the plant as needed. ... It's relatively normal for your cannabis plant's leaves to start turning yellow towards the end of your flowering cycle as the plant becomes nitrogen deficient while creating buds.

Season’s Greetings to you, Nico! And thank you for all you give to the world. I have an emergency, I think! All my buds look fine except that all the leaves are turning yellow – even the small ones on the buds! I am in the eighth week of flower, what do I do?? Thanks, Nico! – Eddie A., via the mailbag at [email protected]


Eddie, greetings to you and – NO, you do not have an emergency on your hands, so rest easy!
The yellowing of plant leaves is simply due to a nitrogen (N) shortage which is a perfectly natural phenomenon as the plants nears the end of its life cycle. You are in the eighth week of flower, so you are likely close to harvest time depending on your strain. Most of today’s commercial strains flower for about eight or nine weeks.
During the latter weeks of flower, the plants have a physiological shift that requires less nitrogen (which is more important at the start of flowering) and more phosphorous (P) and potassium (K). Many nutrient lines adjust their programs to account for this change, and as less nitrogen is present in the feedings the plant’s leaves begin to turn from green to yellow.

Pretty as she is, this Romulan x Diesel may have too much of a Nitrogen deficiency.

However, sometimes the nutrient program is a little too deficient in N and it sounds like you may have a bit of this issue here as the tiny leaves of your buds should generally not be turning yellow. One or two here and there is OK, but if the yellowing is rampant on your buds a boost of N could help. However, if you are just days away from harvest, then you should be in your flushing stage (feeding with pure water only) and I would not recommend adding anything further. If anything, you may want to expedite your harvest and cut down a few days early if you think the buds are really suffering.
In general, around week six or seven (or two weeks before harvest to be more precise), most growers begin flushing their gardens. Flushing is another way of saying watering or feeding with only pure, distilled water. No nutrients are added during this time. This helps the plant rid itself of excess nutrients and additives that build up over time. It also helps to create a cleaner, healthier smoke for you after harvest. Well-flushed buds will dry and cure easier and burn to a clean, white ash when smoked, making all your hard work that much more enjoyable in the end!
Thanks for reading everyone and remember: Grow… And help the world grow, too!

Help us out guys.
what shall I do?

shall I flush them? Should I just put the hose on them till I have loads of run off?
I really don’t know but I’m on week6 flower and pretty early to see this much yellowing.

There is no way in hell those plants are 3 weeks old. REALLY ??? athlete although I did read the post those ladies do NOT have 4 to 5 weeks left and if they do something is seriously wrong and not with the yellowing.

Those plants are at least 50 days at least lol in Flower Maybe 2 weeks at the most 10 days is more like it left.

The ones in the last 3 pics maybe, But certainly not the first several.

He has a serious problem in the middle of flowering that started near the beginning of flowering. That yellowing would ruin my harvest.

Hopefully someone will chime in and help you, Noobie69. Otherwise, go with your gut... quickly ; )

What Strain are you growing, My Cindy 99 takes 50 days sometimes done early, my RG takes 50 days sometimes done early and they all yellow towards the end of their life cycle. All my other strains are 60 to 70 days and always yellow at the end. I've been doing this for over 40 years.

If in Doubt Flush them out if you really think there's a problem flush them and start with a complete nutrient solution, You can't check run off with fabric pots ? Why ?

Anyways best of luck to you.

So you made a supersoil and winged it but can't get into that? How do you expect anyone to help you if they have no idea what's in your soil?

It's most likely the soil you winged. Issues show up in flower when the plant is using the most resources as it starts flowering. If you're soil is whack then you will have problems.

It could be from many different things. Most likely the soil you mixed up. Yellowing leaves like that are not normal at that stage unless the plant is lacking something which could be from not enough of one thing or too much of something else. Nutrient antagonism can lock out nutrients. You are not going to turn those yellowing purple leaves green regardless of what you do. There is no magic in a bottle you can feed them. Just feed, water, and harvest when ready. If you want to add sulfur just add epsom salts / magnesium sulfate. I don't know what the sulfur content is of that Bio Bizz stuff is.

Don't transplant. As for saving those plants, you're going to get a harvest so don't go into panic mode thinking all is lost.

Thanks for everyone’s input.
I flushed them. With like 12 litres of water. Ph6.3-6.5
Run off was around 6.8-7 seems ok right?
Will monitor for a few days.

iminto week 6 flower. Or37 days flower. Strains are all different too. Most are around8 weeks but 1 strain is upto 10z.
Gorilla skittles, amnesia lemon has really gone yellow, another was blue gelato 41 which seems in needs the longest.

So guess just clean water now...or would u still add some N, or Sulphur...to address the over yellowing dying amount of leaves.
I know they won’t go green but to prevent the bud sites from yellowing/dying.

after previously posting this yellowing was quite significant and at this rate I don’t believe the plants will have much left by 8/9 weeks

It sounds like you need to get out of that supersoil you made. Pouring teas or nutes on that stuff isn't going to do much... hence my transplant suggestion (which won't shock your plant as long as you're gentle)... but I see that's not too feasible given the horizontal trellis I just noticed.

Keep us updated, I love information : )

Yes cut the trellis out and took them out today for the flush. Will just try seeing this one through and defo change the soil for a proper store bough one
