Is it okay for me to bring the PH from around 5 up to 7 in one go or should I spread it out over a period of time?

When the PH is 7 throughout the soil, will the plant start taking in nutrients immediatley or over a period of time?

I want to take cuttings off the vegging plant and I know it's better to be slightly nitrogen defficient. Once the PH is normal, should I not fertilize at all, use bio-bloom or fertilize normally until it's better and then flush N out and take cuttings?

Thanks again for helping :thumbsup:
