Lots of yellowing among leaves

I'm in week 7 of veg.

Thinking about flipping to flower in 2 more weeks. Thoughts on that based on pics welcome too.

Growing in FFOF. Water every 2-3 days until runoff. R/O reading is 6.40-6.60. Water with 1 gallon of distilled + 4 mL of Cal-Mag per plant.

But continue to have alot of yellowing among the leaves.

You can see comparison to other plants on their right which have nice greenness.

Some leaves even have some brown on them. Not too many though. What issues may I be facing? Should I be adding some nutes or go higher on the Cal-Mag?

Thanks!

I feel like your camera may be making them appear more yellow than they actually are in real life? If all plants are yellow as the pics show, 9 times out of 10 it's due to a pH lockout. What is the pH and PPM of the soil runoff?

@Kc-JT What base nutrients are you using and how often do you feed those?

and there lies the issue. I feel like a dummy! First grow fumbles. I just realized my FFOF soil nutrients likely ran out about 2 weeks ago. I'm around 55 days since transplant at this point.

Do you recommend just starting the Fox Farm Big Grow and Bloom on my next feed (next couple days), or start immediately with maybe less water since they aren't quite ready for water yet? Or a foliar feed soon before lights out?

Can't believe I missed starting the nutes earlier!! I think I just have upcoming flowering stage on my brain. Speaking of, how long till these plants get back to norm where I should even consider starting flower? Would a couple feedings do it or longer?

@Kc-JT I'd feed the next time the soil dries out. I'd stick with the ratio that the feeding chart says but would probably do a 1/2 dose and would check the pH and PPM of the soil runoff. May take around a week after feeding to see a full rebound.

Sorry about the formatting there! Not sure why it added my pics in that way among the
