Light schedule

Lots of people run their whole veg on 18/6.
Your clones will need more light intensity as they get bigger, but you can stay on 18/6 until flower for most varieties.

I like using 24/0 for vegetative, for bloom 12/12 works fine, but I use 13/11. During one bloom I tried tapering down to mimic natural seasonal changes, and it was a lot of work to keep changing the timer and I didn't perceive any bloom-growth differences.

So you use 13 daylight in flower @simpleleaf ? I run a little less than 12 hours of daylight in flower. About 11:45 daylight. I coordinate 3 timers so I leave a buffer in there, but I do give them a bit less than 12 of light. Do you give them a dark cycle when you flip? I do a min 24 hours of dark, but usually get 36.

My cloner and Veg room are always 18/6 unless I am trying to reveg a plant then it is 24/7
I pretty much run the same, but found I had a strain that made a lot of pistils this year on it. I went to 24/0 in my veg and it straightened out, but switched back to 18/6 over the summer and more pistils. I like a dark period personally. I know they aren’t supposed to need it but I don‘t want my veg running any faster than it does already.

I run the same fifteen minute delays on my lights as well

Yes @MustGro, I'd guess it's strain specific, some strains may need less daylight to bloom. I seem to recall even using 14/10 and it triggered bloom. I have in the past tried an extended dark period by unplugging lights from timers for a day, and I think it does accelerate the development of white hairs, but I don't bother any longer.
