12/23/23 had to move plants location under the lights, P4 looks like it might have been in a higher intensity spot. removed all the shade leaves from the main stem except the top ones on all of the plants. Giving a week for recovery then the amount of darkness will be increased by 2 hours. week 9 will be the first week of flowering light cycle adding another 2 hours of darkness, then week 10 will be the first week of 12/12 light/night.
