Magnesium deficiencies normally don't start in new growth, they start in older growth. Possible broad mites? I'd scope them at 100x and see if you see any tiny critters.

If a deficiency, the ones that appear in new growth are: calcium, boron, sulfur, copper, iron, and manganese. Of those, I'm only familiar with calcium and it doesn't look like calcium to me.

+1 for possible broad mites.

I think I also see white small larvae on the 2 fingers that are in focus.

If you zoom you can DEFINATELY see something there that looks larvae like.

I don't think it's broad mites..

Do you USE a Ca/Mg product when you feed? Have you amended the soil with Dolomite lime?

If not,,,,,use a Ca/Mg at full strength right away. Looks like it's a related pH problem with some nutrient locking started. Your going to need to address the pH problem with some top dressing of a garden lime.....and be sure to pH all ingoing liquids to 6.5 before use.

ok so I checked for broad mites but i didn't see anything but i did pull the plant outside and away from the other girls. I will be taking more pics when i get home for luck. I use to ph my water every time but I'm on a well and it starts off high but after my roots organics it balances out at 6.7 and it always balances out so i rarely check ph anymore and this is my only plant suffering from this. Ill post more pics soon.

thats what i think also. Im also hitting my plants up weekly with neem oil and safer 3 in 1 to keep those pest away.

that damaged growth most likely wont bounce back. Watch for new wonky growth means you still have mites. imo those pesticides wont get rid of the broad mites...spinosad is best
