Anyway,
It sounds like you've got a lot of bicarbonates in your tap water.
Bicarbs will lock out Mg.
It may also be the case that your plant just wants more.

.

i agree its the water

These ones are still in veg. These are in lc mix #1and guano tea recipe. I prefer the lc#1 and guano tea recipe over all other mixes so far. I've tried multiple mixes with the same main problem. From here on out I'm focusing on one mix and it's going to be lc#1 with the guano teas

I don't ph because everything I read said you don't need to in organic soil since the soil buffers it's self from the dolomite lime. That's the reason why I haven't done so

If it was my water source would a normal water filter remove biocarbonates? Or would i have to buy a special water filter or start buying ro water?

I have had great success with the lc mix #1 and guano tea recipe. I grew this one in that mix but I still had the same mag problem. I even started to add 1/2tspn per gallon of Epsom salt to the nutrient teat and it didn't help. I only saw improvements with a foliar feed of Epsom salt. This by far was my best cycle though. I just got tired of the on going mag problem so I switched to dank Frank's mix to see if a new mix would suit me better but now I'm seeing the same thing so im returning back to lc's mix but trying to find a solution for when I switch from veg to flower on my next cycle. Plus trying to fix the current problem in dank Frank's mix since I'm only on week 2 1/2

Similar deficiencies plagued me while transitioning to recycled soil. After reading slownickel(I think) go on about the importance of calcium in several long and detailed posts I started topdressing with gypsum. Things started getting better quick. I now add a spoonful when remixing soil and top dress at transplant as well.
If I recall correctly, calcium plays a role in the absorption and transport of many other key things.
It is cheap and easy to get, worth a try in my opinion.
Good luck.

That might be true of a real organic soil but most indoor people, myself included, are just running organically amended soiless mixes in small pots and calling it organic soil in the hopes that it one-day becomes one.
No a regular filter will not remove bicarbonate.
Manufacturers suggest RO filters will remove 95% of bicarbonate but I can't locate real data.

Im no expert but I only use RO water now or occasionally mix my RO with tap water 50/50. My tap water has crazy high alkalinity. Plus I personally think way to many people reach for epsom SALT way to often and early.

Even the cheapo paper test strips will show how much crap is removed from RO water compared to any tap water. Ever wonder why so many homes have them for ice makers and coffee use etc. ? If you cant locate REAL data try google. Im not going to do it and link hundreds of links for you.

Use 2 caps from a bottle of apple cider on 5 gallons of water to lower down PH,

if you are in organic setup that doesnt mean you dont need to lower a PH of
your feed.. with lowering a PH a plants will eat a lot easier and will not lock Mg..

I think I Wood is onto something with the gypsum, it'd be worth you running a trial. Back in the ROLS thread Coot and them all would rag on folks running dolo lime, and all the fellows dealing with Cal-Mag lockout issues. At one point he mentioned that this situation is incredibly common in folks running in coco setups because coir is incredibly deficient in sulfur. The sulfur is used by the soil microbiological community to break the carbonate bonds on both Calcium carbonate and Magnesium carbonate, making both Ca and Mg available. Without the sulfur, as sulphate, playing this role you can get these lockout issues. It may be good to try and top dress with some gypsum and see if that helps.

Switching your overall lime mix to something like 1 part dolo:1 parts ag lime:1 part gypsum, and then using 1 cup of this/cf of your soil may help. This would be 26%Ca, 4%Mg, 5%SO4, with a Ca:Mg ration of 7:1, which is aight. The 2:1 ratio of the straight dolomite lime is quite a bit off from what you want, being about 22%Ca, 11%Mg.
