Urgently Need Advice on Grow....

NewGuy99 · Nov 24, 2025

My latest grow has turned out to be a bit of mess. It was supposed to be 4 autos but one plant is clearly not (pic 2) and I'm not sure what to do about the light cycle. The autos are on 18/6. But will the regular start budding at that or will I need to swap to 12/12 but won't that affect my autos?

I have three plants at 7/8weeks. (2xautos) And one at 4 weeks in my tent. (1xauto)

I messed up with the neuts and think the light was too strong to start with so one of the plants leafs are destroyed as you can see in pic. Buds looks good tho!! I think I have fixed that issue now.

What should I do here??

I understand autos can flower at 12/12 (never done it). The photo will need 12/12 to flower. So, it might be best to use 12/12 if you want them all to finish about the same time. Another option would be to let the autos finish at 18/6 while the photo continues to veg. Then switch to 12/12 to flower the photo.

Thanks @LoveGrowingIt , how long can a photo continue to veg for?
My autos have another 5 and 8 weeks between them.
Can I let it sit that long before switching the lights to flower of should I be thinking about switching before that? When do you normally switch to 12/12 - what week?
What would you be doing in my situation?

A very long time.

It can easily wait that long.

I'd probably let the photo grow. It should increase the yield. You might even be able to start some more plants when you have room in your tent after you harvest the autos.

I would let the photo ride it out also. Theoretically photoperiods can veg forever. Most people flip when the plants are around half the size you have room for to account for the stretch.
