Do you have any lime mixed in with your soil? It looks like a combination of calcium deficiency and the wrong pH.

No i do not, just straight up coco coir

Okay, do you use nutrients made for hydroponics and is what your feeding pH adjusted between 5.5-6.0? What nutrients are you using and how.

defnitely a cal/mag deficiency i use one tbsp of pelletized lime per gallon of medium(coco) and charge my coco while rinsing i put 5ml in the last 2 gallons phd to 5.8-6.0 and use that for my final rinse of the coco.

just het a tbsp of lime and scratch it into the surface of your coco a few inches and water though i would reccomend using some calmag the next few waterings untill the lime breaks down a little bit, be careful if you happen to accidently use hydrated lime instead of dolomite do not follow my recipe it will over do it and i have no experience with anything other then doloite lime.

Yea i do, advanced nutrients micro grow and bloom, ph level is 5.5. I think i may not be feeding it enough. Since its started flowering i have not raised its nutrients

Im sorry are u talking about just regular lime bought from the store? And squeezing it in? I dont have cal-mag and would prefer not to spend any money on it

well growing in coco your going to have to address the fact that it does not release calcium and magnesium the way soil does, that's why there is specific nutrient lines made for coco and the difference is that they have calmag in them. A bag of dolomite lime from the store (not lime like lemons) look for dolomite lime pellitized garden section for 5-6 bucks and it will last you about a billion grows, no but really it would take 100's of gallons worth of coco to use all that lime at 1tbsp gallon of medium.
Fact is there is no way around needing cal and mag with coco even says so in the feeding chart that gh provides with there line hold on ill get one so i can give you the correct instructions. ok here goes: and i quote " When growing plants in coco media or with reverse osmosis water use 5ml of calimagic per gallon during the first two weeks" end quote,
Even then i use calmag through my grow till mid flower.
If you dont wanna do anything to fix it i promise you those plants will never produce anything but some scragly janky buds and nobody wants that so either cough up $7 bucks for a bag of the lime or 12-20 for any of the different calmag brands, botanicare, gh, go ,pretty much any nutrient place anywhere sells it

Oh woww, thanks, i had no idea! When i bought the soil from the hydro store they didnt even tell me i needed extra nutrients! Ok so i just buy the dolomite lime from any garden store and sprinkle some on top and water it in? How much should i put if i have a ten gallon pot?

Do u think i have a mag deficiency too? I know i could use epsom salt or do u think the dolomite lime will take care of that?

Don't bother adding the epsom salts until you mix the lime in and see how it works. If you do too many things at once, you'll have no idea what fixed (or ruined) things.
The dolimitic lime does contain some magnessium, which is what makes it dolimitic.
Normally you mix the lime in with the media before you start growing so it's part of the mix rather than a topping. It doesn't dissolve well at all so think of it as a time release form of calcium. Follow the instructions on the label or web for tablespoons per gallon and try to mix it in the top of the media.
The calmag+ stuff is more direct and water soluble (calcium nitrate). Just keep in mind that also contains a lot of nitrogen. You could probably just add more of the "micro" bottle as well. I don't really know AN products, but I assume the calcium nitrate is the majority of what's in the micro bottle.

ten gallon pot i would put 10 tbsp in maybe a little less but like i said i stick to 1tbsp per gallon of medium it works for me and many others.You could also use epsom salts but since that would only correct mag and not cal you might as well get the lime which is pretty cheap anyways.

calmag containing nitrogen??? I have a couple different brands and none of mine contain anything but calcium and magnesium no npk whatsoever at least in botanicare and calmag from general organics.

Derived from calcium nitrate, magnesium nitrate, and iron EDTA. There really aren't any other kinds of soluble calcium other than calcium nitrate for hydroponics. Another soluble alternative would be calcium chloride, but plants don't need chlorine.

Dude just spend 10 dollars on cal mag... That's definately your issue, and I'm not sure why people are saying 5.5-6.0 PH cause it doesn't look like you're doing a hydro setup... so check that your soil PH is 6.0-6.8 or so just to be safe and then add some cal/mag to the next few waterings. Definitely not a waste of money.

Okay i stand corrected my general organcs cal mag is 0-0-0 but as you posted there is some in botanicare. so if nitrogen is an issue just buy a brand without it.

I use it as well.. But this is Calcium Carbonate not Calcium Nitrate.
Calcium is often added as calcium carbonate (12% Ca) or calcium nitrate (12-0-0 17% Ca).

i don't see a mag issue, just calcium.
i am assuming that your choice of nutrients doesn't contain enough calcium, so i would look for a calcium specific supplement if anything.
i just found the product i was referring to and it's called CA25 or Calcium-25. google it and it will lead you to what you're looking for.
