Calcium def. 5 weeks into flower?

[Guest]

The smaller leaf is from my grogg bagseed 5 weeks flowering, spots just started to appear in the last 2 days. The plants are still growing healthy buds.
There are no spider mites That I can find and I have 6 or so ladybugs in veg and flower chamber for added protection.

The big leaf is from veg cabinet and is og bubba cloner.

So I am wanting to know if calcium def. is problem?
I am using dolomite and blood meal and bone meal in a perlite vermiculite potting mix(peat based).

Should I foliar feed dolomite lime and water????

This is my absolute first grow and is from seed in a C24 . So I am so close I wanna see them finish.
3 in flower, og/bubba kush,herijuana,and unknown kickass clone( I refer to as GROGG).

>Test your ph. Directions are in my signature below. This is the first step to getting your plant back in shape

>How much dolomite lime, blood meal, and bone meal did you add per cubic foot for example?

>What is the ratio of vermiculite, perlite, and peat used in your mix? Peatmoss right?

>You have not been giving any nutrients in the water? Sounds like your mix is lacking nutrients with just lime + blood and bone meal

>Your spots are a nutrition problem; interestingly your leaf color is a sickly green color and not normal

Provide any other details you feel is important to get you a better answer.

you look like you got pest issues or ph issues, thrips can cause that problem too. How many leaves are affected?

have you tested your soil ph? what brand of soil is it?

thats not a calicum issue by far,

what nutrients are you using how often and how much?

what size pots and how big are the plants?

have you trimmed or pruned them or LST recently?

soil mix etc

soil mix etc

4 gallon deep pots.(actually undercounter blueboxes)
3 parts potting mix (organic)
1 part perlite
1 part vermiculite

2 tbsp/gal- bonemeal
1 tbsp/gal- bloodmeal
1 tbsp/gal- dolomite lime

fert with shultz 10-15-10 at half strength.

The ph is around 6.5
As for the color of the leaves this is from the lighting. The leaves are actually nice and green except for the plant in question.

I think I know the problem. I ferted with full strength shultz last feeding by mistake and just realized it now.

Does this look like an over fert problem on little leaf .


Also here is pic of og/bubba kush, herijuana, and the messed up GROGG.

As you can see it is only on the grogg plant for the most part.The grog he foreground and the og bubba is in background.

Also here is heri on same schedule and feeding etc.

Don't get me wrong. Your plant looks pretty good.

Looks like your getting the slightest bit of tip burn = little too many salts/ferts

How does the shultz measure up? Compare ingredients to this checklist:

In a bloom fert you want:

>1-1-1 ratio nitrogen, phosphorus, potassium or similar; reduced nitrogen so 1-3-2 might work well also; use care not to apply too much phosphorus

> type of nitrogen used mostly nitrate nitrogen and little ammonia or urea nitrogen

>contain all the micros: iron, manganese, zinc, copper, boron, and molybdenum

>contain calcium and magnesium if no dol. lime is in the soil or you need to boost levels

>contain sulfur if no gypsum added at planting to the soil or other sulfur based ferts are used

>potassium chloride not in it; instead potassium nitrate, pot. sulfate, or monopotassium phosphate instead

Tip: If you add epsom salts and powdered gypsum at 1/4 teaspoon of each per gallon of water (3.8L) this provides calcium and magnesium. Your nutrient solution will be complete if it contains npk and all the micros. Using epsom or gypsum also adds valuable sulfur. Add the epsom salts + powdered gypsum every second or third time you use the bloom/veg food when there is dolomite lime in the soil and every time when not or you need to boost levels.

Thx sproutco, I will look into the ingredients but I know that ammonia and urea are part of shultz.

I am planning straight water as of next wednesday for the affected plant as it will need to be flushed for 2 weeks prior to harvest.

Do my veg plants seem ok?
The leaves on 1 or 2 may be burned from sitting against cfl for the better part of a day.



BTW the small blue cup in foreground is a rootbound male og/bubba that will be kept as a future cross breed dad.

 

[sproutco]

Just the very tip of the leaves are burning = a little too much salts / ferts

Be sure to check out everything in my last post.

I think your doing pretty good actually.

You can see calcium deficiency has burned margins and tips usually. Your plant does not.

Thx MNS for your input. Thrips or no see-ums are not an issue as far as I can tell,as this is a fully sealed unit guarded by sticky strips and ladybugs and early flower safers soap spray.

SC thx for the kind words and advice.
Please expand on "CONTAIN"

I just flushed and re-fed half strength shultz and epsom salts. I have sulphur in my well water so no need for more.
I rechecked for bugs and all seems good.


I am flowering the GROGG for 3 more weeks and the heri probably 4 and og probably 5.

 

[sproutco]

Contain = the fert should have in them; all micros for example

Its definately a nutrition issue...too much or too little of somethinga

If you are raising the level of magnesium with epsom and there is potassium in your shultz, you should also increase the level of calcium to keep a balance of maybe 4:2:1 potassium to calcium to magnesium

Hey sproutco thx for the speedy replies, headin to graveyard shift in 10 minutes but get a quick reply in first.
I have dolomite lime in potting mix is this not enough?
1 tbsp per gallon of soil.

I am quite sure it is from double dosing the shultz by mistake, that is where my probs started so I flushed and then added half strength as stated and used epsom as I know I used it in veg for mag def. and cal. def. as I have very very soft water.
I also was self diagnosing from the complete guide to sick plants sticky under calcium deficiency.

Here is bud shot from this morning for the GROGG plant.See background leaves with spots.

When I saw your pic my first impression was damage by bugs..It looks like a bug has sucked parts out of the leaves, what causes those little spots.

Shultz 10-15-10 Click on it to enlarge:


>You can see this particular formula lacks all the micros. It needs copper, boron, and molybdenum. Lack of copper may be giving the plant that awkward green color.

>It contains mostly urea/ammonia and little nitrate nitrogen which is not good

>It lacks sulfur, magnesium, and calcium so this is something to consider

When using the regular npk + micro fert, its good every third fert or so to add epsom and gypsum to the water even with dolomite in the soil. If supplies of cal/mag run low it can be added with every watering/fert.
