fertilizer-nutrients Mineral Deposits on Leaves after Switching Fertilizer to GH

[Yani]

Notice the small white crystal-like dots. On the right is an area I rubbed about a week ago and it left some craters. I'm using GH MaxiGrow. I noticed the Calcium concentration is fairly high. I'm wondering if anyone has run into this "issue" before or someone might be able to enlighten me on what's causing it. Plants look healthy otherwise with no sign of over-fertilization I'm watering w/ 300ppm every 2nd to 3rd time so I'm certain it's not an over-fertilization issue.

I switched my basil over to this fert. also and it is showing some dots here and there.

they look fine to me. whats the underside look like.

The underside is pretty much the same. Under a loupe I can almost certainly say they are crystals.

I'm not too worried about it in terms of harming the plant but was wondering what may be happening.

Also for things like basil I don't want to be consuming something harmful, but I guess if anything it's calcium?

its probably edema. its nothing to worry about.

Good to know thanks! Now that I know how to describe it properly, I'll include a link for anyone who stumbles across this in the future to another thread here on this forum talking about it more in depth:
