Need help wi my cuttings.

i took 14 cuttings 12 days ago and in the last 3 days they have been turning yellow..

i dont know wot it is and would love some info on wot to do..

can i cut the tips off the leaves or is it too late for this.
i have no sign of roots yet and seems kinda like the first time i eva took cuttings.. if i can remember correctly they started rooting just after the two week mark..
i only use a floro tube lite to get them to root. is that enuf for them.

if i increased the amount of tube lites would this help.???

need help bout my cuttings that were taken 12 days ago from plants that were 2wks into there flowering cycle.

as you will see in the pics i posted there all turnin yellow and this only started happnin in the last few days.

since they were taken theve been in my propagator gettin light from an 18in flouro tube lite.. i use this when rooting my clones and have had great sucsess so far lol.
i also mist them with plain water twice a day and make sure the rockwool cubes dont get too wet..
i really dont know wot else to do.

ooops posted two the same threads lol.... thats wot drugs do to you lol..

you should try using root hormones
