I highly doubt your cannabis male pollinated your romaine lettuce. What you see here is preflowers on your romaine. This is refered to as "bolting". Do keep us up to date though by using the canna-curate tag. I would hate to miss out on the biggest news in the plant world if i am wrong, lol.
Lettuce does not bolt in this fashion, atleast accroding to the information i have found thus far! I did how ever take a new picture because guess what.... ITS GROWING CRYSTALS. i'm freaking out right now! This is so cool!
I posted a new picture! Let me know what you think... I'm super intrigued by all of this!
