Septoria? Deficiency? Help me please !

[Eledin]

Im also adressing the clear PK burn he has by the way, is that bad too?

View attachment 2448781 (420cal mag) I didn’t add this the last two feedings But everything else I add together ALONG with some worm castings.

Use it as much as it says in the bag unless youre feeding tap water which I assume you dont cause I said it two times and you didnt say you were. But you need the complete tripart, you lack Base A and Base B from Vivosun which will give you the nitrogen youre lacking right now. Calmags almost always have nitrates to help calcium intake but you still should use a base NPK, charts usually adjust the ammount for you depending on the stage.

 

[Eledin]

Also the PK booster I would only use 1/4 of the dose while I see how they addapt once they have all the nutrients theyre suposed to have. Once everything else is in order you can start increasing slowly and if you see more tip burn and its not exclusively on top (which would be caused by light intensity) it means you need to go to a previous lower dosage.

I’ve only used tap water twice the entire grow and I never saw that you asked. Just felt like I was in court watching you two argue a lil but okay base A and base B I’m tracking on those now

 

[Eledin]

Hahaha sorry about that. Im currently in 3 topics trying to help so maybe I didnt ask you about the water or it got lost in all the messages. So yeah, Vivosun doesnt have a PK booster so they probably already adjust it when telling you to use different dosages depending on the stage, dont mess much with it like I said, max 1/4 of the dose and dont use it until theyve been feed properly for a week at least, right now they want less PK and more N.

Here's what google has to say:
While nitrogen itself doesn't directly absorb or transport calcium, it plays a crucial role in plant growth and can indirectly influence calcium intake in plants. Nitrogen is essential for building amino acids and proteins, which are vital for plant structure and function. In some cases, adequate nitrogen supply can enhance calcium accumulation in plant tissues, especially when combined with appropriate calcium supply.

Here's a more detailed breakdown:

• Nitrogen and Plant Growth:
  Nitrogen is a key macronutrient for plant growth, and adequate nitrogen availability is necessary for healthy root development, fruit set, and overall plant vigor.
  
  
• Indirect Calcium Effects:
  Plants require both nitrogen and calcium for optimal growth. When nitrogen is deficient, it can negatively impact various aspects of plant physiology, including calcium uptake and utilization. Conversely, sufficient nitrogen can improve the efficiency of calcium use by plants, potentially leading to greater calcium accumulation in plant tissues.
  
  
• Specific Examples:
  • Calcium Nitrate: A common fertilizer that combines both nitrogen and calcium, providing plants with both nutrients essential for growth and development.
    
    
  • Soluble Calcium: When used in conjunction with nitrogen, soluble calcium can improve crop production, particularly when nitrogen is in a readily available form like ammonium.
    
    
  • Nitrogen and Calcium in Soil: The balance of nitrogen and calcium in the soil is important for optimal plant health. An imbalance of either nutrient can lead to nutrient deficiencies or toxicity.

In any case you should check for septoria. If you have a magnifying glass or a microscope or whatever what youre looking for is black dots inside the round spots, those black spots produce the spores and look like this

Yeah, I’ve been dosing them with PK pretty well. Every week, doing the recommended amount but started to hold back on cal mag. I haven’t done any nitrogen nuts besides what’s in the cal mag and in the fox farm soil with some grow dots throwing in there. But the soil and grow dots mix was done 2 months ago. That was when I started having bad burns from to much nitrogen nuts. Since I’m a beginner here and this is my first grow I’ve learned a lot. Is there some nuts or brands you recommend through the whole cycle? A lot people said they just use the trio fox farm? Thanks in advance!

 

[Eledin]

Im not from the US and fox farms is not available here so for that hopefully someone from the US will chime in to help you. I see that plenty of people use them though but I dont know if they are the best option or not.

I tried looking at them yesterday throughly and there were very tiny black spots. Though I couldn’t tell if they were septoria or deficiency. But they were all very uniformed. Some smaller than others but were almost perfectly round. These all seem to be non-uniformed which i spent like two hours online looking at different kinds and levels

 

[Eledin]

I mean it could perfectly be the case that you have calcium deficiency, pk burn and also septoria. I just dont think its septoria because many of those spots are present in the edges of the leaves too. If after you start feeding correctly following a chart it gets worse or it gets worse like in a matter of days, like a lot, you should cut the affected foliage, the problem is that it is present even in the upper leaves so... cutting everything right now is not a good idea. You could feed LAB to your plant, lactic acid bacteria, it helps them combat septoria and other fungus. You can make it yourself but it takes a few days, in youtube theres plenty of tutorials, you can also buy it but, here at least, is a bit pricy in a bottle. The most commonly used is lactobacillus.

 

[Eledin]

For LAB you only need water, rice and milk

 

[Eledin]

If its septoria it wont cure it but it will delay it. I dont think there's a good option right now if its septoria, which I dont think it is but I dont know where the other person got the idea that I ruled it out, I was just going to what I think it was first. Still dont think its septoria but there you have it just in case.
In any case its a good microorganism to have in the roots wether you have septoria or not so doesnt hurt.

From google:
Lactobacillus species can be found in plant roots and the surrounding soil, also known as the rhizosphere. These bacteria, which are part of the broader group of lactic acid bacteria (LAB), play a role in soil health and plant growth by promoting beneficial microbes and inhibiting pathogens.

Here's a more detailed look:

• Lactobacillus in the Rhizosphere:
  Lactobacilli are known to inhabit the rhizosphere, the soil layer surrounding plant roots.
  
  
• Beneficial Effects:
  They can produce substances like lactic acid and hydrogen peroxide, which can help control harmful pathogens like those causing root rot.
  
  
• Soil Health:
  Lactobacillus species can help modulate the soil's microbial community, favoring beneficial organisms while suppressing harmful ones.
  
  
• Plant Growth:
  They can also promote plant growth and nutrient uptake by improving soil fertility and making nutrients more available to the plant.
  
  
• Plant Tissue:
  Some lactobacilli can even live within the plant roots and other tissues, further supporting nutrient uptake and overall plant health.

You supplied a great amount of information. I am forever indebted to this knowledge. I appreciate it

My pleassure! But remember that I can be wrong or partially right (100% sure you shouldnt be feeding only vivosun bloom, 100% sure about the burnt tips being light or PK related and fairly sure the spots are caused due to nute umbalance) but you can still have septoria. If you saw those black spots inside the big spots it would be a good idea to prepare some LAB just in case. If 2 problems get together and look alike you might think its only 1 thing.

I tried zooming in with my camera and I was checking it out with my magnifier. I don’t see anything… 2nd photo is of an older fan leaf

 

[RootFarmer]

Are you growing in coco?

To me that look like nutrients not being balanced. I cant see black spots inside the rings and the colors dont look like septoria so I think its not septoria but LAB is great to have anyway, just saying

No sir. Fox farm ocean forest soil!
