need help figuring out whats going on- day 7 flower

First grow so I apologize in advance for asking silly questions but I can't decide if I need to address this situation...I have them in 1/3 super soil, 1/3 mix(ss and roots), and 1/3 roots. Day 7 after the switch.

Pics 1-3 are of the white rhino. Bottom leaves are starting to get lighter in color. Almost a light yellow spottiness.


Pics 4-5 are of the G13 C99. Some yellowing in the smaller lower leaves. Also what appears to be some sort of burn in pic 5. I did burn her with the cfls early on, so that may or may not be the issue.


Pics 6-7 are of the white widow. Lower leaves are looking on the yellow side. Top looks great. (I think)


Feel free to request more pics if itll help.
Let me know what yall think! Thanks!

Sorry, my pics got all mixed up. Pictures 1,4,5 are of the white rhino. Pictures 2,3 are of the c99. White white is still 6-7.

Trim down the lower 1/3 while they are still stretching. That would get rid of the older leaves and get better air flow. Leaves on the bottom are pretty useless anyway. If they start getting too light in the color of the canopy it probably show nitrogen deficiency, but I think your tops look great. Good luck.
