Cal/mag or N?

Cheesedawg plant 2 weeks into flower, this yellowing appeared over only 3 days. In biobizz soil, biobizz nutes, PH 6.2. I've given a dose of calmag but was hoping for second opinion

over fert. you probably don't need to add much in biobizz soil.

At your PH, both cal and mag are no longer available to your plant. With the tips and stripes, you def have a cal/mag lock out.

However, that lock out could also be caused by an over feed.

The severity of the tips and stripes pair with no visible clawing, that I can see in those pics, I'd bed it's just a PH issue. Stabilize the PH at 6.5 and you'll know if it's cal/mag or toxicity.
