What is this on my leaves? Thoughts on plants? First grow

[John Holmes]

Hi, just got home and noticed that my leaves were looking weird, any ideas? Also, thoughts on the plants overall? First grow. Im using coco and GHe trio quarter strength with calmag 5ml every gal. Theyre about 4 weeks old.

Thanks guys

The spotting looks like calcium deficiency to me. Even though you are adding cal/mag, coco really sucks it up. The twist to the leaf also makes me wonder about humidity level or pH. Sorry, still pretty new myself, but those are some potential ideas that occur to me. Good luck getting it sorted.

Any sign of bugs on your plants? Looks a bit like spider mite damage.

My sister told me about a thing called rust. It is a fungus. Check google.
