Is this a sulfur toxicity?

[TheHighwayman]

Howdy! I have been growing some Blackberry and lemon autos, and recently I noticed some strange growths on them. I was wondering if the growth was from a Sulfur Toxicity from well water with a high trace of sulfur in it. Here's my PH and ppm of my tap/well water and some pics of the plants in question.
Any feedback or advice is much appreciated thank you!

PH: 7.92
PPM: 262
PPM per feeding: 300 but recently gave them around 500 ppm with the 262 from the well water.
The girls with the weird growths:

The Blackberry:

Thank you! Is that why the plant has those weird spots?

Which soil are you in? EDIT: I just looked. Try getting that pH down a bit for watering. 6.5-6.7

EDIT again: Also it looks like the Mother Earth Terracraft already has nutrients in it. You may want to hold off on any more MC for a while.

Ok thank you! I just ordered a kit of PH down/up

6.4-6.8 is the ph range that I roll with.

Ph fluctuation can cause that.

Ph fluctuation can cause that.

Oh thank you, my PH kit comes Saturday so I'll get that PH down to around 6.4-6.8 for the next watering. Thanks again everyone!

Those leaves won't recover or change back to looking perfect. The new ones should be back to normal if the pH adjustment fixes the issue.
