Autos 30 days preflower

so these autos are coming up on 30 days, they are showing preflowers. Sensi skunk. I was hoping they would get bigger. Only about 12 inches tall...should I be thinking of switching to HPS lamps now?

What light schedule you running those? From my limited auto experience, you kinda stuck with that as your yield now, but yea change to hps and hope those fuckers stretch.

This is an auto I ran a couple years ago at 34 days.. seems like yours either run longer than mine did or they got stunted some how...

Sorry, just looked at th e logs again and I guess this is 38 days..

seriously that is 34 days? 34 days from SEED? What strain? What soil?

these could be stunted due to a number of reasons

a) Transplanted from SOLO cups - Autos no like transplant
b) Too chilly at night 64 f and that is a 10-15 degree swing from day.
c) Overwatering early on - FFOF holds water too well. (starting to dislike this junk)
d) Autos just are not as genetically stable like Photos.
e) All of the above - plus some

Like I said.. it was actually day 38 (read it wrong the first time) according to the logs from that grow, and I think I was using the day seed popped as day 0. Bubblelicious Auto from Nirvana. Grown in a 50/50 mix of FFOF and Happy Frog with a bit of extra perlite added.

Keep up the N with grow nutes until stretch is over then start adding your bloom. Your temperature swing seems fine; I always imagine autos can take it a bit colder with their ruderalis dna. Really those look green and healthy, nice job.

I second this. Other than being a little small they really do look healthy. I really struggled with deficiencies from about day 25 or 30 until the end (harvested on day 75). Looks like you're doing a better job than I was.
