Does this look like Magnesium deficiency?

[Bob's Auto's]

Hey Guys/Gals,

Could you take a look and tell me if this is Magnesium deficiency?
I've got this only on my OG Kush CBD Auto. All other strains don't display this at all...

I flushed the pots with a nutrient solution of 5.54pH & 754ppm as the liquid that drained had a pH of 5.94 & 1490ppm which is far to strong.


Regards,

Bob

Not that serious but you should be using cal/mag during flowering anyway.

Thx for the peace of mind brother
Tonight I'll make a foliar feed with 0.8gr Calcium Nitrate and 0.4gr Magnesium Sulfate mixed in 1L water.
