Yellowing leaves with brown spotting

Help me please. This is my 2nd grow. Im not sure whats going on with my plant. Im using FF Ocean Forest and then I just added The Soil Makers “EndGame Flowering Mix”. Which i believe is a granular fertilizer with Fishbone Meal, Fertoz, Soil Kashi, Gypsum, Aragonite, Insect Frass, Kelp Meal, K-mag Granular, Crab/lobster shell Chunks, Basalt Micro-fines.

I havnt really figured out the nutrients situation yet

Don’t worry about the lower leaves. It is normal for a plant to shed them as it matures. The rest of the plant looks fine.

I would get pH and PPM meters and begin using them to test runoff each watering. It will help you avoid problems going forward.

Guidelines:

pH in the range 6.3 to 6.8
PPM ~1,000

Does it matter that those brown spots are on a majority of the leaves on the entire plant although you cant see them in the picture.

Are the brown spots on the lower third of the plant? How about close up pics of said brown spots and their vertical location on the plant? The only brown spots I see are near the bottom and shouldn’t be concerning at all.

Take the yellow leaves off, they won’t ever recover. I would definitely be worried about the brown spots as that is not a normal sign of aging.

I see signs of Calcium and/or Manganese deficiency and also, with the lower leaves being affected first, tells me they need more Nitrogen.

The End Game is a Flowering formula which normally uses reduced Nitrogen and increased phosphorus and potassium. The nutrients in the soil are probably used up by now and I agree with @MidwestGuy that you should have a tds and ph pen in your arsenal but with those pots being directly on the ground, it would be difficult to measure any runoff (I grow outdoors too and cannot get runoff from my 45 gallon containers so I just need to listen to what the plants are telling me.

With increased phosphorus and potassium (In the End Game Nutes), that can affect the uptake of Calcium so you get a vicious circle going. Decreased calcium affects the uptake of Manganese…

Study this chart. Pay attention to the examples to help you understand it. Everything interacts with something so we strive to find the balance.

This leaf is at the top. About 4 inches from the tip and the plant is about 6 foot

I expect it is a form of mold. What is the humidity in your area?

Very high humidity. I am in the fingerlakes of upstate ny. Currently 89 %

Certainly mold then. Increase airflow around the plant if you can. A dilute peroxide/water mix can help as well.

What kind of mold are you thinking it is? It doesn’t look like leaf septoria because the spots are missing the tell-tale yellow halo around the dots. But if it is fungal (perhaps rust fungus), H2o2 won’t work… you’d need a systemic fungicide… one that contains the active ingredient Bacillus or myclobutanil.

This is what Septoria looks like:

Since your environment is hot and humid, you can also create a natural defense by adding Lactic Acid Bacteria to the soil (watering it in). You can find my instructions here. It would be without the molasses… just the LAB.

Even if it turns out to be a deficiency and not fungus, the LAB will be a great addition to your soil.

I don’t really know. I’ve never spent time learning about the various forms of mold. I probably should as treatment efforts may differ depending on the fungus.

The only fungus I really understand is trichoderma, but that is because of mushroom growing.

Good point. Certainly don’t use neem oil to attack it. You are near flower and neem shouldn’t be used to treat it.

Do this instead: if it doesn’t help then try peroxide

LOL… that’s me too hahaha…

But, I do deal with different fungus because of all my fruit trees. Seems each one is susceptible to different fungus. Same goes for squash, cantaloupe, and grapes… I normally spray with a copper fungicide but I’ve not had to worry about it on my sacred plants (knock on wood). Most of those are a form of rust fungus.

We had a post on mold on peaches just yesterday.

In the case of this not being fungal. I have been looking at the manganese deficiency and that looks identical to my plants right now. Brown spotting being chlorosis. If this isnt fungal…How would i ammend that? Is there a specific product to fix this like maganese foliar sprays etc. And if so any recommendations?

I’ve been here for years and have never seen a manganese deficiency.

Manganese deficiency normally starts from top down. Potassium def also has chlorosis and brown spots but it wouldn’t seem likely here. With spots being throughout, and the yellowing being at the lower part of the plant, I would suspect natural aging as MidwestGuy suggested along with the Ca deficiency Caligurl mentioned. Just my two cents worth. Happy growing. :v:
