Nasty.........
Plants DO NOT draw moisture into the leaves from the air rather than through the roots, this is pure fantasy!
Yes, light during the dark cycle is causing the flowers to re-veg, that is why they look funny.
Could also be messed up from growing from 12/12 from seed, which is quite effedup for cannabis.
Either way, you still have some weeks before these are ready, wait until there are 98-99% brown pistils before harvesting.
