Magnesium deficiency

[Gator]

Just transplanted and now this,any suggestions???

Check that pH is correct for your medium.

[Gator]

pH is good

[Gator]

Cal- mag and water maybe???

[Gator]

Strain is glue sniffer, I've had nothing but issues with this strain, but my girl really likes it

[Gator]

Medium is pro- mix,ewc, and perlite, using nftg nutes and cal- mag

Also watch you are not overwatering. This can also cause that problem

You know what you are doing Gator . Maybe it's strain specific issue? Either a different pH or different amount of CalMag than your norm?
When I grew in soil I always kept my pH between 6.0-6.5. My personal opinion is yours is running a little high. Maybe GS likes a lower pH?

Or maybe thats one of those cheap ass PH/moisture meters with probes that stick into the soil. I started with one of that type and soon found they are not accurate.
PH shown IMHO is a tad high for veg, ok for flower

[Gator]

I'm going to feed them this morning and try to get the pH down to the 6.4 range hopefully she will recover quickly

Magnesium is typically available to the plant at higher pH levels so either your pH is low, you have a lack of another nutrient not allowing its take up or too much of another blocking it, or it's not a magnesium deficiency, perhaps manganese or phosphorus. Yellow blotches on leaves can be a boron deficiency.

So I'd be getting a quality pH meter like an Apera ph60 for starters and go from there.

I have a blue lab pH meter
