Quick opinion plz

So here are my outdoor autoflowers. The first one and biggest is auto big bomb. My main concern is with this one. With today's feed of Botanicare kind bloom low dose of kelp me kelp you and also small dose of beastie bloomz I gave it calimagic to. Because I think I have a Calcium deficiency. Am I right? If not then what do you guys think the spots are. My pH is 6.5 runoff and my tds-3 says that the PPM are around 700 but I think my PPM meter is off. I'm using Pro mix HP also by the way this is my first time feeding beastie bloomz and only at 1/4 strength. The second one is auto dark devil. Seems a little stretchy to me. The third one is autoberry. Last week I accidentally snapped the main stalk about 3 inches above the soil. But I immediately taped it up and staked it up and fed with superthrive. And has had growth sense but I'm sure I stressed it. The run out on all of these are 6.5 pH

I see it on the tree leaves behind the plant aswell. Is there a hose being used nearby?
Maybe getting a little off spray from the hose onto your leaves..?

No hose or any spraying of any kind near by. In the country in the woods. Responded well to the feed and dose of calimagic 48 hours ago. Will pist pics soon but still damaged leaves. No idea what it could be.
