Marijuana Indoor growing experiment progress and updates! A week later, slightly yellowing leaves!!

Hey everyone. Mary-jane guru's assistance here please Hive account@budman Hive account@rebeccaryan Hive account@pingapete Hive account@allowisticartist Hive account@ganjafarmer Hive account@ganjagirls Hive account@rawpride #tuck-fheman ! My plants have turned yellow the bottom leaves it seems. I am not over watering them have not increased at all, been the same since the start I just wonder now that they are in flowering state the 'make shift' lighting is now no longer sufficient?

The top leaves also seem very spindly, however they are still flowering..

What I have also noticed is the top leaves seem to be curling into each other for some reason and I cannot for the life of me work out why, but can only assume it is a lighting issue and they are needing a different fuller spectrum?

The indica in the middle seems very yellow and the leaves seem to be very long and thin. They are still under cfls around 14 - 16 hours a day..

Top leaves all curled up.

All and any suggestions would be much appreciated. Thanks a ton in advance.

Free the weed.
