Leaf issues after corrections

[Justpassing]

Hello all,

I noticed yesterday that one of my plants, Super Lemon Chunk, has this yellowing on the fan leaves.. They are towards the bottom and as you can see the upper ones are curled up a touch. I have flushed them all to remove the ph lock issue I was educated about on here. This was a couple weeks ago and the rest of them are doing well. Not sure at all what is happening with them, I used bag seed years ago and never had any of these problems so I'm confused. I have flushed them with Epsom salts with ph corrected water, 1/4 strength nutes once a week. So nothing crazy. Any ideas? Suggestions? They are under a 400w mh light about 20" away from it with a fan blowing near by but no on them directly, just moving any heat away.

Thanks !! Just want my girls healthy.. PS she was Fimmed a few days ago.

Did you drop any nutes on your leaf? The curled up is Mg problem.

Nope, for sure I didn't. And she was just flushed with Epsom salts a less than a week ago. I used 5mg per gallon I think it was.
