Hi folks, A complete newbie here looking for some guidance. I recently started my grow project roughly ~3-4 months ago so that the California march ~12 hour light cycle could induce flowering. Thank goodness it work! They are flowering but unfortunately the weather is a bit sporadic ranging from sunny days to pre-june gloom conditions. I recorded the temperature last night at 58 degrees F. The plants are beginning to show signs of stress (yellowing of the leaves) and irregular leaf developent. I'm wondering if the cold nights will affect THC production. Should I bring them in at night and prune the yellowing leaves? Here are some pics.
