So I started my new seedlings they have been growing about 3 weeks and I didn't notice but lights were still on 12-12 and they look like they are already starting to bud. can I change lights back to 18-6 or did I mess these up?
You can change your lights to 18-6, but if they started to flower the plant will have to go through a re-veg stage. The leaves will look weird for awhile until it kicks into veg.
So I changed lighting back to 18-6 after 1 day they look like this anything else I should do? should I just scrap these and get new seeds?
I'd grow those out. Back into 12/12. They're gonna take at least a month to revert to veg, grow out the funk and get back on track. Good luck!
They're tired from the extended light that they're no longer accustomed to. Dim or raise your lights if you're gonna keep rollin with them at 18/6. Sent from my SM-G975U using Tapatalk
