One plant yellow.

So I had dealt with some calmag deficiency and got it almost under control. All plants back green except one occasionally gets some a small rust spot or two. But it has slowed way down.

but the gorilla glue plant is turning yellow still and idk why. Picture of ur from side and canopy of the rest of the plants so you can see how different the colors are.

Was it Calcium deficiency or Magnesium deficiency?

Both had yellowing bottoms and tops were getting bad rust spots.

Ahhh, so Calcium deficiency. What EC of of Calmag are you giving them?

 

[SlobOnMyKnob]

I am giving them 5ml of cal mag/ gal in RO

Got a close up of a few of the leaves in natural light?

 

[SlobOnMyKnob]

I took a couple off the plant to bring our and get pics

Actually it looks like it's magnesium deficiency.

Okay how can I boost magnesium without calmag. It’s obviously not doing enough

Up your ppm of calmag and reduce your nitrogen input.

And it’s odd it’s just one of 6 plants. Only gorilla glue gun plant. Also I just watered and it usually takes about a gallon to run off but today only about half gallon.
