Glass Slipper, 33 Days into flower, orangish weltering

Glass Slipper Strain from seeds
Medium: Coco
600W Lumatek, HPS
33 Days into Flower
Watering with dasani the entire grow and nuting every other water. Plants have been beautiful up until now and this is only happening on one plant and one side of it. I think it's either heat or light and have moved the lamp cause I think this one stretched itself to getting burned...?

31 Days into flowering cycle...

33 Days into flowering cycle...

As you can see the other plant isn't affected at all, so i don't think it's nute burn or deficiency. But please feel free to offer your thoughts! TIA!

And here's some tasty plant porn for your hungry eyes....!

it looks to me like a boron def , but boron usually starts at the top . boric acid at 1 teaspoon per gallon( eye wash )will fix it if its indeed boron . it has the rust red tent to the leaves and everything associated with that def . ive never exp'ed it myself .

Micro nute defs. are rare at best. To have one you most likely have another base problem that has caused it!
I would check the pH of that site!
Run a Ca/Mg if you don't!
Coco? Be SURE to run a Ca/Mg with that!
Your N looks a tic high in all the plants, but that doesn't look to be a problem so that is not related to this at all (you don't NEED to fix that).

Thanks guys,

I flushed, pushing good 6.0 PH, I am adding CAL/MAG in the Coco during feeding. After a day the yellowing is going away. I believe it was the light, after moving it I am having some results, will post the repair pics later; they are sleeping right now.

this is true , usually lack of phos and potassium sets off boron def . no matter u seem to be on the mend , good luck.

Welp, the stress continues, the yellowing didn;t go away, it wasn't a light problem, silly me.
It's either a deficiency or a burn, I am guessing a deficiency because I am using straight Coco.

Anyone else have any other thoughts? suggestions?, I am at about 42 days into flower
Should I leave it alone and get what I can from it?
