Fox farm soil and nutrients.
Almost looks like could be different issues. Have you checked really close for mites? That center pic looks slot like them to me. I’d do that first thing if you haven’t
Check regularly for bugs. There are none.
Are the leaves bronze and with dark brown leaf spots?
Yes as you can see in the pictures.
Where do I find a support ticket?

Soil in pots, Hydroponic, or Coco?
PH of runoff or solution in reservoir?
What is strength of nutrient mix? EC, or TDS
Indoor or Outdoor

It’s called brown leaf spot or leaf spot fungus you need to call in @garrigan he’s got a whole thing about it might help you even though it’s pretty much all about outdoor plants there’s some general guidelines that might be useful, I’m fighting it too and it’s awful … also @Hammer might have some input ? …hope it helps
I believe I found out what you problem is
PHOSPHOIRUS ( P
Phosphorus (P) Mobile Element and Macro Element
Benefit: Phosphorus does a lot of things for the plant. One of the most important parts of Phosphorus is: It aids in root growth and influences the vigor of the plant and is
one of the most important elements in flowering as well helps to germinate seedlings.
Phosphorus is an essential plant nutrient, and since it is needed in large amounts, it is classified as a macronutrient. Phosphorus is a MAJOR important nutrient in the plants reproductive stages. Without this element the plants will have a lot of problems blooming without proper levels of Phosphorus.
When your plants are deficient in phosphorus, this can overall reduce the size of your plants. Not enough causes slow growth and causes the plant to become weak, to little amount of Phosphorus causes slow growths in leaves that may or may not drop off. The edges all around the leaves or half of the leaves can be brownish and work its way inwards a bit causing the part of the leaves to curl up in the air a bit. Fan leaves will show dark greenish/purplish and yellowish tones along with a dullish blue color to them. Sometimes the stems can be red, along with red petioles that can happen when having a Phosphorus deficiency. This isn’t a sure sure sign of you having one though, but can be a sign. Some strains just show the red petioles and stems from its genes.
So pretty much the overall dark green color with a purple, red, or blue tint to the fan leaves is a good sign of a Phosphorus deficiency. Having Cold weather (below 50F/10C) can make phosphorous absorption very troublesome for plants.
Many people get a Phosphorus deficiency confused with a fungus problem because the ends of the leaves look like a fungus problem, But the damage occurs at the end of the leaves. side of the leaves and has a glass like feeling to it as if it had a ph problem. Parts affected by a phosphorus deficiency are: Older Leaves, Whole plant, Petioles.
Too much Phosphorus levels affect plant growth by suppressing the uptake of: Iron, potassium and Zinc, potentially causing deficiency symptoms of these nutrients to occur def in plants. A Zinc deficiency is most common under excessive phosphorus conditions,
As well as causing other nutrients to have absorption troubles like zinc and copper. Phosphorus fluctuates when concentrated and combined with calcium
Problems with Phosphorus being locked out by PH troubles
Cold wet soils, acid or very alkaline soils, compacted soil.
Phosphorus gets locked out of soil growing at ph levels of 4.0-5.5
Phosphorus is absorbed best in soil at a ph level of 6.0-7.5 (wouldn’t recommend having a ph of over 7.0 in soil) Anything out of the ranges listed will contribute to a Phosphorus deficiency.
Hydro and Soil less Mediums
Phosphorus gets locked out of Hydro and Soil less Mediums at ph levels of 6.0-8.5.
Phosphorus is absorbed best in Hydro and Soil less Mediums at ph levels of 4.0- 5.8. (Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Phosphorus Deficiency.
Solution to fixing a Phosphorus deficiency
Some deficiency during flowering is normal, but too much shouldn’t be tolerated. Any chemical or organic fertilizers that have Phosphorus in them will fix a Phosphorus deficiency. If you have a phosphorus deficiency you should use any N-P-K ratio that is over 5.Again Peters all purpose 20-20-20 is a good mix. Miracle grow Tomato plant food, Miracle grow All purpose plant food (Only mixing at ½ strength when using chemical nutrients, or it will cause nutrient burn!) Other forms of phosphorus supplements are: Bone meal, which is gradual absorption, I suggest making it into a tea for faster use, where bone/blood meal is slow acting, but when made into a tea it works quicker! Fruit eating bat guano, which is fast absorption, Worm castings, which is gradual absorption, Fish meal, which is medium absorption, Soft Rock Phosphate, which is medium absorption, Jamaican or Indonesian Guano, which is fast absorption. Crabshell, which is slow absorption. Tiger Bloom , which is fast absorption.
Here is a list of things to help fix a Phosphrus Deficiency.
Advanced nutrients Bloom (0-5-4)
Vita Bloom (0-7-5)
BC Bloom (1.1-4.4-7)
GH Flora Bloom (0-5-4)
GH Maxi Bloom (5-15-14)
GH Floranova Bloom (4-8-7)
Dyna-Gro Bloom (3-12-6)
Fox Farm Tiger Bloom (2-8-4)
Dr. Hornby’s Iguana Juice Bloom (4-3-6)
Advanced Nutrients Mother Earth Bloom (.5-1.5-2)
Fox Farm Big Bloom (.01-.3-.7)
Earth Juice Bloom (0-3-1)
Pure Blend Bloom (2.5-2-5)
Pure Blend Pro Bloom (2.5-2-5)
Sea Island Jamaican Bat Guano (1-10-0)
Indonesian Bat Guano (0-13-0)
Rainbow Mix Bloom (1-9-2)
Earth Juice Bloom (0-3-1)
BIO BLOOM (2-6-3.5)
AGE OLD BLOOM (5-10-5)
ALASKA MORBLOOM (0-10-10)
METANATURALS ORGANIC BLOOM (1-5-5)
Any of these will cure your phosphorus deficiency. Affected leaves will not show recovery but new growth will appear normal.
Now if you added to much chemical ferts and or organics,( which is hard to burn your plants when using organics) You need to Flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients.
Note: Blood Meal, Dried Blood, Guanos, Kelp Meal, Cotton Seed Meal, Peat Moss,
Sulfur and fish meal are all acidic and can bring your ph down, so if you add these please monitor your ph when using those.
Note: Bone Meal, Rock Phosphate, Wood Ashes pretty much all ashes, Shellfish Compost and Crab Meal are all alkaline and can make your ph go up, so if you add any of these please monitor your ph.
HOPE YOU HIS HELPOS
Thanks Will, he’s got the eye for pictures ! Way better than mine, I’m glad it’s not leaf spot fungus even though mine looks exactly like that first picture, I’ll put it up when I find it
Edit: you might want to check this thread just in case
Thank you so much for your help. You are obviously very knowledgeable. I wish there was someone close to us that was.
Thank you also but for indoor I think he is right. It’s so nice to have some help from this forum.
@Paranorman, Thank you for the he kind words. Many deficiency’s can look and act and cause other deficiency’s. As you ell as the PH
@Dahlia, That’s why I’m here, I have been here now for over two years now. as love what I do here and that’s helping others. What you posted makes me feel really good and it puts a on my face. And make me wants
Our Ph may be a little low. Bought a meter but it doesn’t seem to work. The water alone without nutrients reads 5.8. It has never been a problem until now. The only thing new is 2 Foxfarm soils mixed in stead of Dr Earth.
@Dahlia is your meter digital? or a probe type …If it’s the probe type .they are notoriously inaccurate . But if that’s what you have ,here’s a couple of help full tips …use steel wool and polish the probe tip good .and check the ph 2-3 hr’s after watering .and dry the tip good so it wont tarnish so fast ,is digital . clean Very Carful with a tooth brush, soft one, and use some of the test solution to clean with … .Don’t dip into the solution bottle …Pour a small amount into a shot glass to dip the brush into …then dispose of this used solution after… and Dahlia what is the ph of you feed water .? Hammer
Your problem is moist likely …Nutrient !
N deficiency. Go get your self some plant food man and those will go back to green quick.
Here a pic of N Deficiency
@Dahlia .And there is someone close at hand to help . The Whole ILGM team is at your finger tips . And garrigan62 is a heck of a soil guy .and top notch at deficiency’s … Sincerely Hammer
