probably most likely too much nitrogen/ heat stress / not enough fan leaves left on the buds for them to fatten up so the plant will grow more leaf then fat buds if you remove them
I am just not sure... this is my best guess from the pictures.
Can you elaborate on any possible timer issues or light leaks... I want to say this is 100% re-vegging but theres only so much one can say from a few pictures!
THE BEST WAY TO CHECK FOR LIGHT LEAKS: Simply go into your grow space right before the lights turn on, and close it up, and see for yourself if there are any light leaks. It should be BLACK... even the tiniest amount of light can trigger some strains to go back into veg mode.
Anyway, I am not sure on this websites policy about linking to other sites, but I'll post anyway.
Here is a thread about a guy who revegged a cut he took from a mature flowering plant.
Look at it after 2 weeks of being under veg... it looks kind of similar to your plants.
Hey guy so my skunk plant is in flowering i'd say it has 3 weeks left but i wanted to make sure this was normal, if not let me know what you think it is?
