Is this contagious?

Hi,

I posted earlier this month about the same problem but it seemed to persisted to almost every other plant in my garden. I'm wondering if it's a virus but I feel like that's highly unlikely. I suppose if I'm using all the same medium, the plants would all react the same right? I'm using coco/perlite/ Gaia Green All Purpose and Power Bloom. Next grow I'll do a 50/50 split of coco/soil. Anyways, here's some pictures of what I mean. If there's anyone who knows how to fix this that'd be awesome.

You might need to add some.

Yeah I think you're right. Thanks for the tip after looking on the forums more. I found someone who's doing the same grow medium as me. Like you said, he said he's just started adding some calmag and things got better. Hopefully that's the case for me as well. LOL anyways,
thanks for your help and have a good one!
