Hmm, got a few questions for opinions..

Is the stretching due to not enough light(ive been successful with less), or just genetics?
They did seem to be growing well and keeping side growth down, but after it touched the cool tube it began to slow. Im thinking it did this over night before i could adjust and forced the side growth to try and take over. they are probably sativa dom.

There's about 14" of grow space. I think i just need to get a hold of some autoflower/indica/ruderalis strain, or up my space...

In the mean time, im thinking of chopping the tops and letting them root in plain water. Staying on 12/12, once the roots hit the water ill introduce nutes. So since its a mature clone this time, think itl go straight to flower or stretch the same? if thats the case, i can do an extra low scrog from 12/12 instead.. what do yall think? lights on in a couple hours, so if they grew anymore and havnt sex'd i may have no choice. will update when they are up.
