I'm currently 40 days into veg. Growers choice 680 led. All female seeds. 3 gallons pots.
One of my plants seems to be turning yellow and don't know why. I haven't fed them any nutrients since I transplanted them. Only have fed water and orca once a week. I'm currently running my light at 14" & 40%. Do they you guys know what I might be doing wrong?

My first thought is they are hungry if they have been in the 3 gal for 40 days and you haven't feed them. How long have they been in the 3 gals?
What is the pH and PPM of the soil runoff?
Need a little more info, most important the medium ppm and ph. Looking through the pics and different leaves one spot looks like magnesium deficiency, another spot looks like zinc deficiency, the tops look low in nitrogen or not enough light, seen two spots that look like pest damage. Need a little more info my friend.
I retract my previous statement. you would see yellowing leaves from the bottom up.
Calcium??
What's your medium? Looks like nitrogen but based on what you grow in may determine lock up or lack of . . .
