Please help with lighting situation

Hi I have two 48" gro lux lights n two spot gro.

I have two mature clones at 30cm with pistols n two clones that seem to be made up entirely of pistols at like 20cm and tons of offbranches (tiny)

15 n 25 cm ams n arjans haze 3 with a few shoots are from the seedling (feminized)

Now you can see my paradigm. What an odd mix, well this is my first grow and I have tried to absorb everything.

But would ams and Arjans haze be able to adapt to 12/12 from 15/9 while the others finish the cycle then increase it again(if yes then how much)?

The clones were more for getting into the groove and to under stand how they grow, so please any information would be great, n thanks!

Ps: I'm on an iPhone, I could email image but it's impossible on this otherwise.

dont quite get what your asking, but if you talking about adjusting your light cycle without throwing plants in and out of veg and flower ive heard that you can do it by slowly changing your lighting cycle... not something abrupt that'll prompt flowering...

Hm thank you. You are on the dot.

So if it's 15 hrsnow how much should I be lessening it over how long? (I have it on a timer)

Just lessen it by an hour everyday until it gets to the right cycle you want.
