Its usually not a problem. Cfl dont penetrate the canopy well so it is probably just the new leaves that dont get enough light. I trim them off.
The spectrum you using is more on the blue side which is perfect for veg. Have you tried a lower kelvin like 2700k for flowering?
For winter I start alot of ladies by cloning and let the veg inside for a while then I move them outside to to flower. This is apart from my normal cycle in my flowering cab.

A sog is sea of green. Its a perpetual grow where I harvest every 3 weeks. Smaller qty but constant harvest. Ive also been trying to keep costs down. I have been adjusting my cab for over 18months. If you need info or advice just ask. Ive been doing it a while.
You should really look for the digital timers at builder's. The waco ones are R160 but very reliable and it stores the time incase of load shedding.

Ahoy nev. Welcome to rui. Looks like you getting the hang of it. The colour on the lady looks good. What strain is she? Looks sativa to me. Bag seed in our banana Republic would prop be a malawi or some swaz gold if it was a decent outdoor strain. Keep puffin.
