So is it sulfur?
and POTASSIUM DEFICIENCY are two very different deficiency’s
This is Phosphorus
This is Potassium k
Take a look at my very first pick I posted at the very top and then look at what I just posted
Ok, so it’s potassium, then. Yeah, I can see that now.
I did and still say potassium @garrigan62
Yes it is. And all of you have been awesome and I Thank You all so much. I hope we all got something from this and. I’m sure we all did.
And you are. You hit it first time out.
That was a really good way to keep us on our toes. Thanks, @garrigan62.
That’s what it was all about. And it only took 1/2. A day. Not two weeks…lol
So how are you going to resolve it? Top dress your soil?
I used Miracle Grow Flower Food.
Very fast acting.
With. N = 15%
P = 30%
I use that in my garden for my roses. That should definitely do the trick.
Oh ya I treated her this morning.
Thank you @garrigan62 for the schoolin
Always have held you in high regard
Thank you again this was very cool
And right on @Sittingbull64 have learned much from you and @raustin and @Aolelon
All of you are a wealth of information and have helped me along in my grow journey
Thank you for your kind words. We are all into this togetter. And we all learn from each other…that’s what it’s all about hete at ILGM.
It’s me who has learned here…and @garrigan62 is right, we are all in this together, there is no me in team…it’s a team effort…what you don’t know I may know and if I dont know @raustin may know…well you see my point…said it before, this is one awesome forum site!
Thanks for that lesson. I have a terrible time trying to diagnose deficiencies. I often see leaves on my plants looking like the manganese photos you showed. Thankfully not at the moment. How would you treat that to fix it?
Outta likes guys
But I love it!
I was gonna say sulphur, too. And I’d have been wrong.
@AnneBonny I HOPE THIS HELPS
Manganese (Mn) Micronutrient and Immobile Element
Manganese Helps enzymes break down for chlorophyll and photosynthesis production,
as well as it works with plant enzymes to reduce nitrates before producing proteins.
Having plants that are deficient in manganese can turn the young leaves into
spotted (mottled) yellow and or brown areas on young leaves. Dead (Necrotic)
yellow spots form on top leaves, while the lower older leaves will or may have
gray specks and or spots. Symptoms can include yellowing of leaves while the
leaf veins can stay green. Can also produce a chequered effect. As the plant
gets newer growths the plant will seem to grow away from the problem, that’s
why the younger leaves may be unaffected. On the top of the leaves, brown spots
can appear. While the severe areas of the leaves turn brown and wither.
Parts Affected by a Manganese deficiency are: Young leaves.
Too much Manganese in the soil will cause an iron deficiency. The blotchy leaf
tissue is caused by not enough chlorophyll synthesis. Your plants will seem to
have very weak vigor caused by the excessive amount of manganese.
Problems with Manganese being locked out by PH troubles
Soil ph of over 6.5, High iron soils, Low nitrogen Soils, Dry weather
and compacted soil.
Manganese gets locked out of soil growing at ph levels of 2.0-5.0
Manganese is absorbed best in soil at a ph level of 5.5-6.5 (Wouldn’t recommend
having a soil ph of over 7.0 in soil) anything out of the ranges listed will
contribute to a Manganese Deficiency.
Hydro and Soil less Mediums
Manganese gets locked out of Hydro and Soil less Mediums at ph levels of 2.0-4.5
Manganese is absorbed best in Hydro and Soil less Mediums at ph levels of 5.0-5.6
(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 manganese deficiency.
Solution to fixing a Manganese deficiency
Foliar feed with any chemical fertilizer containing Mn., or mix with water and water
your plants with it. Any Chemical/Organic nutrients that have Manganese in them will
fix a Manganese deficiency. (Only mixing at ½ strength when using chemical nutrients
or it will cause nutrient burn!) Other nutrients that have Manganese in them are:
Manganese chelate, Manganese carbonate, Manganese chloride, Manganese dioxide,
Manganese oxide, Manganese sulfate, which are all fast absorption. Garden Manure,
Greenssand are both good sources of manganese and are medium/ slow absorption.
Now if you added to much chemical nutrients 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.
