Light burn or deficiency?

[Bigsledge310]

This is a bubblegum auto that’s 5 weeks from seed. This morning I noticed a few leaves had this discoloration that wasn’t there last night. I raised the LED light just in case but if it’s not light burn please let me know. Thanks!

So those brown spots aren’t uncommon? I haven’t had it happen with my other grows but they’ve been outdoor

Looks like mg def, get some CalMag.

Those autoflowers are like little race cars from my experience they like to feed high and heavy.

I’ve been using calmag with every feeding 3-4ml per gallon

PH?

BigSledge what's you Ph?

You may have had a deficiency when the lower leaves were new, that's not affecting the upper leaves now.

Definite problem but it might not spread.

They look slightly overfed. The serrated edges are curled too, what temp is the tent at?

Ph is between 6.5-7.0, the tent temp is around 77F, the issue seems to have been resolved now, not sure what the deal was a week or two ago

Are you using foliar spray of any kind?
