little mutation nothing to worry about
I saw that you use Plagron, great brand, but be careful
Sugar Royal contains a lot of nitrogen, it's a 9-0-0, and the Cal Mag is a 5-0-0. If you add Alga Grow, which is a 4-2-4, you have nitrogen disproportionate to the rest. Luckily, you're using a little, but be careful, an over of nitrogen could happen.
