Problem

[Tiger mom]

Hi there.I am new to this and this is my first grow.Growing White Widow XXL from Barney's.
She is growing in a tent DWC and has been doing great until now.
She started getting brown spots mostly on newer leaves.She is about 9 weeks in now.
I'm thinking CalMag deficiency but not sure.
Any help would be greatly appreciated.

I don't understand your EC reading. Is it 1.487 or is that the ppm's?
Your pH is way too high for DWC.......should be 5.5 - 5.8.

It's 1,487.

I'm having a problem holding the ph steady.It seems to vary between 5.8 and 6-6.1.

That can't be an EC reading........it has to be PPM's.
