Funny thing is, I checked the runoff pH but not the mixing pH DOH!
What's an ideal runoff for soil?
Thanks.

Ok so should I just make sure the mix pH is from 6.0-7.0?
I'll do that as well, I don't do it as much as I'd like to, but I'll let the water sit more often now.

Yep, looks like mag def due to Ph fluctuation to me. Its kinda a hassle to PH your water every time you... water, but it needs to be done. I Ph my water to 6.0-6.5 I dont like to see it go any higher than that and the runoff should never go above 7.
I give food every second or third watering, that way you get to wash your roots and prevent salt build up/nute burn.
I would just continue as is, making sure to ph your water every time.
But of course, this is just my opinion and your mileage may vary.
Good luck and happy growing.

If you dont treat the deff it will die eventually from it since you are so far away from flowering. epsom salts 3/4tsp per gallon of water will correct it. Do this until its gone
If it doesnt get better then it could actually be a calcium deff but it dosent look to be that so far.

Ok I'm planning on a flush for all the plants if the runoff is below 6 or higher than 7. Thanks again.

Runoff is @ 5.0-5.5 pH!
Flushing all plants tomorrow and on 3rd time flushing, hit them with a little less than 1/4 nute flush.

I'm using the Fox Farm lineup, I just think I overdid it a bit, especially since the pH of the soil is already off
You think Fox Farm is bad shit?

FF is fine though it wasnt really formulated for pot like Advanced nutrients or General Hydroponics is
Your soils p-h being so far off is likely the issue here. More soil should buffer the ph better but for some reason yours is wayyyy off track. Flush it out well with no nutrients. I dont normally reccomend flushing with NO food but when something is that far out there I will.

Ok I just gave them all a nice flushing/watering, I hope it fixed it, most of them are getting transplanted next week anyway
Thanks for the help.

While we can all agree that epsom salts contain magnesium, however you need to look at the cause of your deficiency. In this case, PH lockout. By throwing alot of nutrients at a problem you're just asking to burn the shit out of your plants when your ph does balance out. Foxfarms makes quality products and their nutrients should contain more than enough mag and other micronutrients for your plants, but they will only absorb them within a certain ph range.
I jacked this chart from THE INTERNET!!! As you can see, your plants ability to take up nutes is directly related to the PH.
Be patient, settle your ph issues first, and the mag def should fix itself.

You'd better put it back! Somebody's going to be looking for it, and we'll all get in trouble!
