preflowers at 30days old

can anyone tell me why my plants are showing preflowers at 30 days old. i've never seen this before can someone help please.light is on 18 and off for 6

its normal.its nothing to worry about,just continue like normal.some strains show later,but some will at around the 30 day mark.

Are you saying this is too soon? I've heard of it after 3 weeks sometimes.

yes i've never seen plants at 30 days old show preflowers not under 18/6 lighting. i know they will show preflowers under 12/12 of lighting

Preflowers at the node is a sign that your plant is starting to Sexually Mature. It means your plant is a teenager.
