Not sure what im looking at

[steve970]

I'm currently growing some hella jelly! Bought them as clones,about 3 weeks in. I've notices these streaks on some of the leaves. They are rust colored streaks. I'm using for farm oceanic blend and fox farm nutrients. Any suggestions would greatly be appreciated!

Should i increase my nutrients or is there a specific product for this problem. I looked at the fox farm label and it doesn't say anything about calcium levels.

I'd turn the light down and give them a longer dryback between waterings.
