1st off @Joshua1313 if you c ould fill out this support ticket the best you can it can help with figuring out what is going on. My 1st thought is what is your ph of nutes/water going in and and out. @garrigan65 has seen it all maybe we can wake him up

Was working on it old one…lmao

Looks to be calcium
Here are a couple of pic’s

CAL%2301

CALICIUM%20%234
Calcium (Ca) -Macro Nutrient and an Immobile element.

Calcium is another important element that helps the plants cell walls, cell division in
making the plants stems, stalks, branches stronger, as well as contributing to root growth,
mostly the newer root hairs, Calcium also helps enhancing the uptake of K in the the plants
roots. Calcium moves really slow within the plant and tends to concentrate in roots and older
growth.

When plants exhibit a Calcium deficiency the younger leaves are the first to show it as well
as older leaves. The Leaf tips will die back, the tips may curl, and growth of the plant is
stunted. The plant can show a weakness in the stems and branches, as well as a under developed
root system that can lead to bacteria problems with roots dieing off. Having slow plant
transpiration rates can aggravate the uptake of calcium. Make sure your soil isn’t very acidic,
for calcium gets harder to be absorbed through acidic soils, Which leads to having a plant that
is deficient in Calcium. The leaf tips, edges and new growth will or may turn a yellow/brown color
that happen in spots and often surrounded by a sharp brown outlined edge and then the leaf tips die
back. If too much calcium is given at an early stage of growth it can stunt the growth of your plants.
Having to much of calcium will also flocculate when a concentrated form is combined with potassium.
The parts affected by a calcium deficiency are the roots. Stem or petiole, young or old leaves.

Too much Calcium will lead to other micronutrient deficiencies. Calcium fixation is caused by many
types of mediums such as: clay soils, unbuffered coco and humus. The lime tends to bond to these
soils very easily. The stems of the plant will not be able to hold the plant up and will exhibit
a white brown in between the veins of the leaves when having too much calcium. Also having to much
potassium and or nitrogen will cause a calcium lockout.

Problems with Calcium being locked out by PH troubles

Very acidic soils with excessive potassium, dry and or wet soil. Lack of calcium in the soil may
cause too acidic soil. This may cause to Mg or Iron deficiency or very slow stunted growth

Soil

Calcium gets locked out of soil growing at ph levels of 2.0- 6.4
Calcium is absorbed best in soil at a ph level of 6.5-9.1 (Wouldn’t recommend having a ph of over 7.0 in soil)
anything out of the ranges listed will contribute to a
Calcium Deficiency.

Hydro and Soil less Mediums

Calcium gets locked out of Hydro and Soil less Mediums at ph levels of 2.0- 5.3
Calcium is absorbed best in Hydro and Soil less Mediums at ph levels of 5.4-5.8 (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 Calcium Deficiency.

Solution to fixing a Calcium deficiency
To fix a calcium deficiency you can treat by foliar feeding with one teaspoon of dolomite lime or
Garden lime per quart of water, Or Any Chemical/Organic nutrients that have Calcium in them will
fix a Calcium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause
nutrient burn!)
Or you can take crushed up dolomite lime or garden lime in a gallon of water and water it in the soil.
1 to 2 teaspoons per gallon of water, which will be slow acting. Garden Gypsum, which is medium absorption.
Limestone, which is medium absorption, Rock Phosphate and Animal wastes which are both medium/slow absorption.
Note: Caution when using gypsum to an already acid soil (pH that is less than 5.5) can have a very bad effect
on different types of plants by effecting the absorption of soil aluminum, which is poison to plant roots.

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.

What does the side that is not facing the deck look like? Is it still spreading across the plant, or has it not moved? Are the leafs effected getting worse as in crispy yet? The leafs on the bottom interior are not the same issue as on the leafs on the exterior of the plant. The bottom interior leafs will start to fade as plants grow. I think you have two issues.

First is very minor over-watering. Its why those top leafs are sagging let it dry out some and feel your plants container when it starts to feel lighter then water.

Second I am guessing is not caused by you or your methods. Deficiencies rarely show up on leafs of different ages all at the same time overnight. They also rarely show up in different zones of the plant all at the same time overnight.

Here is my thoughts so follow along… if you foliage feed with a spray too late in the day the sun will cook and burn the leafs in the areas that had liquid sitting on it. The liquid will magnify the sunlight and cause it to kill the leafs in those spots.

Now… if you are “not” seeing that on the side that is against the fence that faces the lawn”… I am going to say you have a male cat that pissed on your plant to mark his area late morning and then mid day sun cooked it… that is why the burn damage is mainly in one spot down low around where a cats butt would be and misted up over the side of the plant that is facing the deck. Does it smell like urine? If so keep that cat away…

Thanks guys it doesn’t look to be spreading at all I think something might of fell on it off the barbecue it’s like this red dust on the top of it might of blew on the plant the spots aren’t spreading just looks like the leaves might stay like that will they heal or fall off will it kill the plant?

The leaves are burned from liquid being on them and then the sun cooked the leafs. It will not kill the plant, but those leafs with the most damage on them are going to die off. It would not hurt to removed them now and leave the few atop your plant with only tiny burn dots.

This is not going to kill your plant, but those leafs being removed will help her take in more light to the leafs behind them that are still growing.
