Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.

Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

What do you think about a Copper def? https://www.royalqueenseeds.com/blog-copper-deficiency-in-cannabis-symptoms-and-treatment-n828 This is the only thing I can find that matches the actual pattern of whats happening. I would guess this is from a ph problem as opposed to a lack of actual copper though

Keep in mind intake and transportation are directly related to foliage color but there is like a range of green the foliage can have...And it's like when your feeding with water not everything gets used and the plant intakes water with nutrients... It doesn't like pick and choose which nutrients it's needs. It intakes water and nutrients..

looks good. but yea your not deficient.. it looks like excess.. overfertilization. Very dark foliage.. On a scale of Healthy Green to Dark green to Yellow there is a whole bunch of wiggle room for colour leaves are suppose to look like but that is too dark.
