Calcium deficiency

Are there any home remedies for cal def? I used a bit of molasses in plain water in between my last two feeds. But I don't have any cal or calmag nutes. I know epsome salt adds mag.. What can I use to add cal? I use the flora series. And ph is between 6 and 6.5.

Calcium carbonate is calcium carbonate.

Have you tried it on cannabis?
Seems like a good idea.

Yes. You won't cure the damaged leaves. Suggest foliar spray to quickly address. Calcium is immobile in the plant. It can't transfer it to where it's needed like nitrogen is. This is why regular feedings throughout the grow in feedings are recommended. It helps with root growth in veg and stem strength as well.

I put about a half a teaspoon of epsome with my normal nutes. I also added a little less nutes than usual bc I don't have a ppm meter and this Dark Angel strain from Crop King seems to be a bit finicky about nutes apparently. I've given all the rest of my plants (different strains) the same ratios. Without climagic but the reg nutes I use have small amounts of cal and mag. I'm hoping this fixes the problem. If not and I can't get it under control with what I already have then I will let the plant go as long as possible before chopping.
Hoping it will push through at least another 3 weeks
Yes, I know epsome salt is mag.. I also added a half of a tab of the rollaid

grind them up pretty fine, like sand, and they'll work, but it is slow release. gypsum and dolomite lime are usually pretty readily available, and not too expensive. a small bag of either ought to be around 5 bucks, and should last you quite a while at the rate you'll use it.

Thanks, I'll give it a shot. Actually I have some calmag RAWbrand but it has nitrogen in it. 9-0-0. If I add it won't it mess up my ratio of NPK mixed with my flora series?

Its too late to do this. And I learned about egg shells for this never heard of sea shells, but I live in my parents basement and dont get out much so....
Botanicare is a 2/0/0 cal mag and might be a better option since in flower.
In your pics I only see one dot out of all the dots that look like a calcium problem.
If I had to vote by the pics I would say its a phosphorus deficiency by the blotchy leaf not sure what the bigger brown dots are.
I would get some microbes to add and stay on track since its only on a few leaves.

i think it could be both. OP, are you letting your soil dry out good between waterings? wet soil causes P problems. i'd raise my ph a little too, try 6.3 to 6.8, centered at 6.5

I do add microbes... once a month
And I believe the dots are mag def
It hasn't gotten worse so I must be doing ok.
These issues seemed to start after I added so.w extra light to the mix. I'm using a 300 watt UFO LED (watt output is 160) so growth was slot slower than it could be so I added a few LED house lights. Growth is picking up

Well, what are they?
When I looked up mag def a few pics popped up that looked pretty simular. They are spots of color change on the leaves not eggs or marks from anything. What else could it I just started giving the plant small amount of koolbloom witch is 0-10-10. So I've been giving it more phos.

Idk Ill guess p or a micromutrient. Only you know what your actually doing with what you feed it. You need to figure it out. The spots are not going to turn green again, you need to watch the new growth and old to see if it continues since you are making adjustments then with that info you will be able to determine what it was. Or at least what you did saved the day. Changes are slow in soil so its not going to happen overnight. You cant learn if you dont fail.
A possibility might be since you had lights that are low in watts and you watered it really good but the lights keep you back you could have developed a root issue. Maybe microbes once a week would help that.
You dont have a ppm meter so maybe what you feed is too hot what water source do you use. all these things matter.
when in doubt flush it out. renute add microbes leave it alone till it dries up again. Your in flower so the nutrient level needs to be up there so I wouldnt cut that down to half strength or something like that. 3/4 strength add microbes. If you had a ppm meter I would say renute at 750 ppm.
Research microbes - research humic acid for your micro-nutrient needs. get a better light.

Your def right about those things..
After I noticed the spots and yellowing I did flush it and refed with reg nutes plus calmag supplements. Since then I havnt had any extra damage pop up. This is my first grow til harvest. I've grown a few through veg but had to get rid of them so this is my first experience with flowering.
The water is tap water (dechlorinated) phed between 6 and 6.5 with flora nutes. I have the sample pack so I'm also using the florablend.. koolbloom.. And others. I was thinking about readding the florablend to the line up for this specific plant even though it calls for none after 3rd week of flower. The recommended nutes seems to be working fine for my two other strains.
All plants started flowering at the same time but the one I'm having issues with has the biggest buds so far. You may be on to something with the weak light source and the root issues. I've def smelled a little mold smell coming from the plants but I've heard it's normal.. maybe I'm watering to frequeently. Ugghh so many different possibilities
