My outdoor AUTOs in soil/perlite are 10 cm (4 inch) tall, 30 day old, have 4-5 pair of leaves, and are FLOWERING. What the …. hell???!!!
It happens at times. Autos flower when ready. I have had them go to flower in 2 weeks and some as long as 8 weeks.
I’ve had them flower early an turn out to be a nice big plant. 4 to 6 weeks about the norm. Can run longer as @ painfree mention. Good luck with you’re auto
Any point in feeding them flowering nutes now? they are so small, will they get bigger during flowering?
Plants look healthy I would definitely start feeding flowering nutes. Keep taking care of them . Good luck
Something probably just stunted it a little. Like mentioned autos prome to that.
You are actually in preflower, which will last about 2 weeks before full on bloom.
30 days from sprout to preflower is common, pictures would really help.
