Plants yellowing way too fast starting flower

[THCMonster]

I know about the bokashi fermentation but I’m so new Into growing (less than a year) I haven’t given it a crack yet I get mine from @bokashiearthworks on IG.. The owner of the company Brandon rust is a regular on cheaphomegrow podcast. Not sure if you’re familiar with it but it’s pretty informative.. but with ur knowledge and the way ur garden looks u may not need any advice . Also a little good news no need to ph up my water is 7.5 and 40ppm out of the tap, so even with 60ml of molasses it only brought me down to 6.3..

Well i actually make my own nutrients from scratch! So believe it or not fermentation is the name of the game for me! Thats why its surprising to see you know about bokashi, because its very similar to what i do, the only difference is that only 1 of my fermentations is anaerobic, the rest are aerobic fermentations!

I would highly recommend you learn as much as you can about how that bucket works and everything breaksdown, it will help you greatly in the future for your grows! Especially if you use microbials!

Also a little good news. I didn’t even have to ph up my water. It’s 7.5PH and 40PPM out of the tap, so even with 60ml of molasses it only brought me down to 6.3..

Glad to see you didnt have to use ph up. A lot of people dont know about the natural ph down known as MOLASSES, lol

Most people use the ph down in a bottle which is phosphoric acid, even though its perfectly fine to use, sometimes it can throw off your nutrients because it is a nutrient itself!

I don’t fully understand the way everything breaks down but I want to learn everything I can.. I want to eventually build my own super soil and have living soil so I can let the soil work for me.. I also want to run a soiless mix organically because the rate of growth on coco grows that I see is amazing compared to soil..

I never knew that molasses was a ph down. that may have been why I had been using the growers recharge every watering with molasses on my last grow and never had any problems.. Maybe the two were balancing each other out.. I was using amino acids to lower ph then use growers recharge then I would put molasses in and the flowers smelled amazing.. the only thing I changed was the langbeinite and the first run I accidentally put in some jacks 10-30-20 before I knew it was organic and it actually did pretty good (well I don’t know if it contributed or not but people swear by it including CAP) but that was it..

I'm in the same spot brother.
When you say to use molasses.... You mean from the supermarket right?
I'm on my fifth grow and every one of them has had this yellowing!
It Started in week 3 of flower and I'm now into week 5

Any molasses will work realistically... But a lot of people swear by blackstrap molasses.

But yea the molasses at the grocery store will work!

But i would check the ph of your soil, cause if you soil in the proper ph range then it could be just a nitrogen problem, which if your trying to stick organic the you can use wormcastings, or if you have a hydro store near you look for a product called nature nectar nitrogen.

But if your ph is too high then i would definitely use the molasses on EVERY watering until the ph stablizes

If you decide to run coco you cant amend it with organic matter and still treat it like normal coco! The moment you add organic material to coco (worm castings, bat guano, kelp meal, etc...) the composition of the coco will change into something more resembling dirt unfortunately. This means you wont be able to water everyday and not worry about problems and you wont be able to keep the coco moist like coco can stay.

If you want to run organics in coco properly and run it like normal coco you have to use liquid organic fertilizers, and only liquids.

The only amendments you can add to coco is mineral based (sulfur, lime, Langbeinite, rock phosphate, etc...)

So be careful how you go about it once you do decide to go to coco!

Not saying you cant amend coco, just saying once you amend it with organic material you cant treat it like pure coco anymore!

Looks familiar brother.. have u done a slurry test, like someone recommended I do at the beginning of the thread? U in soil or soilless? This thread has a lot of knowledge in it, I’d recommend reading it in its entirety.. we look like we’re experiencing the same problems. Best of luck homie..

So to slurry your medium correctly, you do what...?
I've seen those pH meters you can put in your medium with a I long probe on them, are they any good?

I started from the start and I have to agree, very good info. Thanks man you too

I'm running a 50/50 soil/Coco mix and get an average of 4 Oz per plant and I know I can do better I just can't get there yet lol.

One thing I have been doing to prevent early yellowing is adding a top dress of Espoma Iron-tone (about 1 tbls per 5gal of soil)-added at week 1 of flower. It is iron and sulfur. This will drop your ph a little so take that into account. It hasn’t caused me any problems (I have plenty of lime in my soil), and I haven’t had any early yellowing since i starting adding it.

You dont have to waste your money on those! You can test soil with a standard water ph tester.

Put about 1/4 cup of dry soil that you want to test and add that to a clean cup. Add just enough water (distilled water gives more accurate results) to make the soil inside the cup like a slurry, or just until the soil becomes the slightest bit liquidity. Stir the dirt water mixture for about 20-30sec then test with the PH meter. It will gibe you an idea as to what the ph of the soil itself is suppose to be!

Compare the reading from the ph pen to the proper range for what media you are using!

Very simple!

I would hope you dont water your media mixture the same as people tell you to water coco. Cause if you do thats where you could do better!

Once you mix soil with either peat or coco based media it becomes soil as a whole!

You could get much quicker growth out of pure coco with 20-30% perlite added in. You just have to learn how to properly pot it and grow with it!

I have helped many people people on here get really great results out of coco.

If you are interested in giving it a shot just send me a private msg

Hey @Kushymane i would highly recommend taking this persons advice!

You can pick this product up at almost any Home Depot/Lowes or Hardware store/ garden center/ hydro store.

This actually wouldnt be a bad thing to add!

It wont fix your PH issue but it will green your plants back up over time! (As long as the ph gets under control)

 

[hobby4life]

So I did a slurry test and my PH for the medium came back at 6.3
it's not my medium causing my yellowing issue, so it's a nitrogen deficiency?

 

[THCMonster]

Well the deficiency is either nitrogen or iron, but its not going to fix itself over night, it takes time!

If your whole plant is evenly yellowing the. Its nitrogen, but only certain areas of the plant are yellowing then its usually iron.

But the thing is that you probably have the iron and nitrogen available! But because your ph was 7.3-7.4 your plant wasnt able to uptake what is actually available!

So now that you have brought the PH back down, you could probably give it a good boost of nitrogen and iron on the next feeding and it will correct itself over time!

When your soil is that alkaline it doesnt matter how much nutrients you add in, the PH is locking the plant out of being able to uptake them.

Now that its back in proper PH range then just give it some food! Now it can actually properly uptake the nutrients its deficient in!

But it will take time. You will know if its working when the yellowing leaves start slighty getting color back and no new leaves turn yellow!

Give it about a couple days to a week. If it continues you will need supplements

So this might sound silly to ask but my flower nutrient is 20-8-30 and my veg nutrient is 28-8-30 or something close to that... Would it hurt to use my veg nutrient to help with the nitrogen boost as the other ratings on P and K are the same ?
I have been using calmag (2nd grow with it) thinking it was either calcium or iron but I've had no change. So I guess it must be a nitrogen def as it's yellowing from the bottom of the plants up

 

[THCMonster]

You can use grow... 20-8-30 should be enough Nitrogen personally, it could have been because you have been PH locked for so long that it didnt up take what was there.

But using grow wont hurt you, i would only use it no more then 2 feedings though because you dont want too much nitrogen when you are in flower! It tends to inhibit the flowering process for your plant! I would use the grow, monitor the PH to make sure you stay below 6.5, and in about a couple days to a week if the yellowing fan leaves dont start to green up dont worry! Cut them off the plant (at this point they are wasting energy for your plant) and monitor the plant to make sure the yellowing doesnt continue to get worse!

Does the plant look like its a least getting somewhat better?

THCMonster with that real coco info ! Preach brother.
