Yellowing?

[mooons]

Hey guy, the girls are tiered into 3 gallon bags, a little late as they had roots on th bottom of the solo cups. Now they are starting to yellow from bottom up. They were just given nutes (bio biz line) this past Monday. Any help would be great. My ph pen is down and needs recalibration, badly. But here's pictures any help would be great.

Light 50w black star ufo, about to switch to my Mars reflector 3 pannel.
Soil in solos jiffy plant starter
Soil in 3 gal bags miracle grow organics (I know, I know its garbage but I was on a tight time frame...) also has vermiculite 25% ish

I believe they are about 28-32 days old...sorry I know I need to keep better notes.

A this is a slightly better picture. Heat has been 68-78 f. I can't say exactly when this started because I was on vacation for 5 days after transplant. Humidity has been 46-36%. I'm guessing ph issues or nutrition deficit. Does this sound about right?

..Mooons, they were stunted and starved from the looks of this one,... now that it's in bloom, there's little growth to be had; feed her bloom nute's, mild dosage... yellowing is mostly N defc.,... basically, too little too late! Next time just plant direct into final pot; tiering is fine, if you time it right, no root cramping... That starter soil has zero nutes, BTW, so if you keep them in the cups for more than a week or so, they need to be feed lightly....

Okay thanks you for the response. See that's what I get going on Vacation! Well I'm buying fem beans next time so I won't be scared to plant directly into final containers. And they will get nutes earlier. Stills on a learning curve hah. Thank you.
