nute burn or deficiency

I have 2 bag seed plants going currently. Both from same mum. Both planted and sprouted the same time. Both of them in 100% perlite hempy's.

The first one looks good, the second one has some yellowing and brown spots. Now i am just pondering. Is this nute burn or a deficiency. I have looked at the charts. But im not sure. Can someone have a look pls.

Currently they are being fed 1/4 strength culterra foliage 6:1:3.

Nute burn. I'd get something more appropriate for flowering plants, specifically 2-1-1 during seedling.

But these are not flowering? Or do u mean seedlings are better of with flowering nutes?

man just chill. you might of slightly burned but not a big deal AT ALL. Just let the plant do its thing.

They might be root bound time to transplant possibly

Yea. Getting ready to transplant. Not sure on the rootbound tho. The leaves were like that since the first set of leaves. And i had hempies twice as large in the same cups b4. But that being said. Each plant is different. So im not ignoring the advice. Thx

Not nutes burn. But an lack of nutes. Npk. Add some good nutes

Not close to root bound. I got foot monster in cups.

Looks like early signs of a Magnesium deficiency too me.

Thanks. I was suspecting deficiency. The leaves look like a cal mag is needed. Im on 1/4 strength atm. Will up to half?

I prefer 2-1-1 for the seedling stage. Deficiencies don't show up as discolored tips.
