I could use some help identifying please

[Kdmoore28]

I had posted before thinking I had a magnesium deficiency. I changed my feeding to reflect what I thought and I’m still getting some leaves like this. I’ve looked at so many pictures and drawings I’m just second guessing now.
Can someone please share what they think.

thank you.

Looks like a little Nute burn by the way the tips of leaf margin is burnt and you ph is slightly off with the way the leaf has curled off to one side what’s your ph in and out do you check your run off . Od

Thanks for the reply and sorry for the late reply I've been away working.

here is a link to one of my other posts if you don't mind looking.

This is Magnesium deficiency right?

Hi guys I'm pretty sure this is magnesium deficiency. I'd just like a confirmation or correction if anyone could. These leaves came off the lower inner part of the plant, thats all i found on the otherwise healthy looking girl. Thats her just after a Trim, Canucks Northern lights FEM, 2 weeks...

I use auto pots so there is no run off. These photos were taken with a feed EC of 1.8 and a PH of 5.9.
the link i provided was an EC of 1.4 with info listed in the post


again thank you for your input
