They might be autoflowers which flower when they mature, regardless of the light cycle.
I will take better pics tomorrow.
they are auto flowering seeds from auto flowering plant. plus that light spectrum tends to induce early flowering as well! is my guess! ive grow auto flowering… they usually start after a month. those leafs are kinda saggy… might be a sign of over watering also man…its what it looks like in the picture. could it be possible your over doing it on the water? they look healthy… but a tad droopy… and if it is over water… it stunts the roots a little. also might be a tad hot in there. looks good tho!
