Indoor yellowing leaves

Hello Guys I just grabbed clones from purple city Genectics . I transplanted them in 3 gallon pots I’m currently using roots organics original.
I have 54 cookie plants

We are using 12 315 watt sun system lights
I used Mykos when transplanted to avoid from getting shocked.

I noticed yellowing on some leaves .
Can it be a cal mag def ???
Roots Organic has many nutrient so I’m kinda confused

Pretty sure is not a water problem . I always check soil .

Day 3 of Veg Only 3 plants are showing yellow leaves

How well rooted were these clones when you transplanted them? The one leaf tip looks nitrogen burned.

To be honest some clones were well rooted while others were barely showing couple roots . I know that’s a mistake . Btw its my first time indoors . Every new grow I will learn something new . Learn from my mistakes . So please cus me out what should I do next time . When I transplanted I literally threw them in the 315 lights for 24 hours I Believe that was a mistake ??? Please don’t hesitate on cussing me out I want to learn Thank You

No cussing. Be patient and don’t toss them. Mist instead of watering unless the medium gets dry. Weak light is all they need.

Well not going to lie the soil does dries up like in a day also I’m not watering all soil just the middle . So no mist? Since Everyday the soil dries up. Weak light how would you recommend? Can I leave like 3 315 lights on or is it still too strong . I have 54 plants in 3 gallons pots in a 12 by 12 room it’s pretty big or what you mean by weak light

Also forgot to mention some of my babies have a purple stem was reading an article that it can be Mg deficiency Heat or to cold. transplant or even light burn.

A lil bit of cal mag wouldn't do them harm

yeah thank you i just added some cal mag looks like they are getting better.

If they're drying everyday you can/should start to just soak the pots and give them a few days to dry, helps the rooting process

You don't have to mist anymore if they're rooted, unless you want to foliar feed em something or whatever.

If it was me, I would foliar feed them with 1/2 tsp epsom salt per gallon of distilled water to immediately treat the deficiency, then do what Sm4shMAN said, and up your ca/mag dosage so they get more magnesium, or what I would do is add a supplement of epsom salt to your base mix even if you are already using a ca/mg supplement because none of those ca/mg supplements ever contain the right ratio of magnesium that a cannabis plant really needs!

I only grow under 315's, you need a lot of cal/mag. Also when I veg I veg under half the lights .. so in my 7 x 10 room on my 4 x 8 tray I have 6 lights .. only 3 get lit up during veg.
