Maui Wowie

Thinking outloud. You have them on a schedule where they aren't getting enough darkness. The plant has evolved with darkness and does certain processes in the dark period. Including repair. 8 hours of darkness or more creates healthy plants. 6 is considered the bare minimum for healthy plants. Plus the shock switching them to 12-12 when you go to flower is going to make them stretch like crazy freaking out. We have to accept the fact the plant has built in protection mechanisms against light. Its called photoprotection mechanisms. When the plant is getting adequate intense light it gets 'full' then it shuts down (photoinhibition). If the light is too much, they shut off instead of damaging themselves. They get exhausted. If its already shut down, blasting it with more light is a waste of energy and light stress for the plant. Evaporating water from the soil etc. The plants evolved to get all they need in a short day. After 10-12 hours they are done and just take a nap. In a normal day a plant out in the open may get a 10 hour photosynthetic period where its active, then nap time. Some plants near the equator shut off for a couple hours mid day to not take damage. The further you are out of sync with the plants biological reality, the more the stress on the plant and its health suffers. Healthy plants get a healthy dose of scotoperiod growing shorter, bushier with tight internodal spacing. Preflower stretch is minimized. Yes the plants form is different with scotoperiods longer than 8 hours. Its just a way gardeners can control the growth form of the plant, prefering the plants energy go towards other types of growth besides growing stem.

Hey a hawaiin! I put Maui Waui in a 4 way cross, and have been selecting for a couple generations. I keep that bite from the Hawaiian when its smoked. That big, mouth filling flavor because of the novelty of it.
