Can Mg def do this?

It's a bit of both magnesium and nitrogen ziggaro, get some nitrogen and magnesium in with your bloom ferts everytime you feed and you will be fine.

Use small amounts of nitrogen though, do not use the amount you would use in veg, use 1/2 the amount.

So It's been a week since I added 1 tsp EJ grow/gallon and 1 tsp calmag/gallon and the problem has gotten worse. The yellowing is almost to the top of the plant, and i've lost 5 or 6 sets of fan leaves praying for magnesium and then dropping, and my other plant looks so much frostier now :/
I have been waiting to fix it until the soil dries out so I don't give it even more stress.
So today I watered with plain 6.6 pH water because I thought maybe I had lockout, and the runoff read 550 ppm and 5.7 pH. I also have noticed the green leaves feel weird. Could these problems be associated to the pH?
After I saw the pH was low I watered with 7.4 pH water and it came out 6.5 and I'll check it again later
Same specs otherwise

Your ppms are low and your pH is low. Earthjuice is acidic, so when you mix your nutrients let it sit out for 24 hours prior before using them, the pH will rise.


Use 1 tsp per gallon of the grow and 1 tsp of the cal mag everytime you feed, mix them together and let it sit for 24 hours and if you have an air stone, put it in the gallon and let it bubble the mix for 24 hours.

Test the pH before it sits out and after 24 hours......
FFOF is supposed to be pH balanced, but since your nutrients are acidic it's causing the pH to go down, which is why you need to let the nutrients sit out a bit.

The problems could be assioated with the pH, but your ppm read out is far too low for the size of the plant, should be around 100-200 higher for the size. I am sure it's not helping that is for sure....

pH will cause the leaves to feel weird and crispy and other problems.


After I saw the pH was low I watered with 7.4 pH water and it came out 6.5

See! There was not much of it left in the soil........ so you may or may not have to changing the pH after feedings due to earthjuice being acidic.

So depending on the final pH value of your EJ you may not need to adjust your water pH at all.

So I've been trying to fix a magnesium def this whole time and nothing seems to be working. The leaves are curling up and falling off 5-6/day now.
I know you say my ppms are low but I didn't mention I'm using a hanna meter and hanna converts differently.
I found this in the bible:
Hanna 1 mS/cm (EC) = 500 ppm

The pH seems normal now (water goes in 6.8 and came out 6.8) but the leaves keep dying and for some reason this is the one with the biggest buds :(

Also I fed today with a mix I started bubbling 2 days ago with about 1 tbs grow with 1 tbs bloom 1.5 tsp catalyst 1 tsp meta K in 1.5 gallons of water and it slowly rose to 7.1 pH which I adjusted to 6.8. I added another ~100 ppm with some epsom salts, and the mixture came to 500 ppm

If your ppms are 550 (0.5), that's equal to 770 (0.7) on my ppm meter. I don't know what scale Stitch uses.

550ppms(0.5) = EC 1.1 = 770ppms(0.7)

using ppms on organic soil with organic nutrients is an iffy proposition. It's more straightforward with chem, with organics the solution will generally be stronger than the ppm reading suggests.

Also, if you transplanted small plants into 5-gallon buckets of FFOF, they probably didn't completely utilize the nutes in the soil in the month before you started feeding.

The third picture in your original post certainly looks like over-fert to me! The plants are dark green, and the tips of almost every leaf on the plant are burnt.


:D

thanx doc i have heard the same thing with organics, and i'm not discounting it except it does not feel like a burn. These leaves have lost all of their stiffness, and only when they dry out and finally drop off that they turn crispy. Also, the color is light brown, vs when a burn happens mine have been darker and remind me of the burnt end of a cigarette.
Also, the tips are white with some reddish I don't know if you can see that from the picture.

I'm sorry, correct me if I'm wrong there is a lot of misinformation out there

Also, if I am burning, is it correct to say they cannot be flushed? All of my growbooks recommend flushing once a month, but I constantly see it said "there is no buildup in organic like there is chems" and even on EJ's website it says that

A flush everynow and then is good for the plant, not a flush type where you have nutrient burn, but where a lot of run off comes out.
