Let me start out by thanking anyone who helps for their time in advance. I’m new to this site and to growing in general.
I am at 2 months in veg since planting seeds. They are random sensi seed bank feminized photoperiods. Fox farmhappy frog soil. Emerald harvest 3 part nutrients.
i am beginning to see discoloration on some leaves, worse on some plants than others.
Any info you can provide is appreciated.
Looks like calcium deficiency. I’m not familiar with that line of nutrients but the micro should have calcium in it. Calcium in soil is best taken up by the roots when the pH is between 6.2 and 6.8. If you’ve been pHing correctly then I’d pick up a cal-mag supplement.
After looking closer you also have the start of a magnesium deficiency which makes sense because the two require the same pH at the root zone. Cal-mag will fix both.

Will this work despite it saying use just before bud development? I’ve honestly never used cal mag I just had this sample bottle given to me by a local grow store...
that middle plant seems a bit finicky,now me and my own personal opinion is foiler spray that plant with epsome salt a little after lights out,give plant time to col down after light out,if you have feed all the plants the same that one is finicky,i wouldnt add any thing to the feed ,the plant looks of nute burn on tips,so that plant i would just water next round and watch the new growth for 3 days,if the new growth doesnt look better then i would add epsome salt to the feed for mag,most soils are loaded with calcium and mag,its the balance that keep it right,if you over feed something it doesnt take much to lock them out,like i said just my opinon
The spotting will stop however the leaves that are already damaged will remain the same but shouldn’t get worse. You will see the symptoms of the magnesium deficiency disappear since you caught it before any physical damage occurred.
