Help if this is a problem

This is only on two leaves of 4 plants should I be worried

Slight nute burn. Lay off feeding for a week.

Na. You cool bro. Just back off a bit. Do you own an EC meter?

This is my first grow I'm using god berry clones from a mate doing hydro in a 60x60x78 tent with 600 watt digital ballest with mh in for the next few weeks

And thanks I'll keep an eye on them the next week or so

I've also invested in a multi meter ph, moisture and light but waiting for shipping

It's slightly overnuted. The N tox is probably causing mild phosphorous and potassium lockout. I'd just water it for a week or two instead of feeding it, at least until it recovers.

Edit: Oh, wow, this is hella-old. Nevermind.
