Yea, they did start off like due to lighting. Lucky as heck they bounced back, your extremely correct on that.
What bank did you get your seeds from? You probably could get away with the same strain from a different bank that has a longer flowering time. I would run forwards the problem though while your mind is still fresh from that grow. Thought about ditching the GPD next grow, but figured I need to at least get one nice grow off of em. Dropping only one next grow though. Got about 12 seeds left and ready to make some magic with them! IMO
