@420 has you covered on the lights. I would just leave both on myself.a question about my new lights. They have a switch for bloom and veg atm I have both turned on is this right or should i just have the veg turned on ?
As to the root farm nutes, you should be fine with them as long as you don't starve the plants or, perhaps more likely, lock them out. I would just follow the manufacturer's guidelines for mixing, and then dilute down to your target ppm/EC. Mix them in the order suggested, and mix well between components. I would start at ~200 ppm or even less, and plan on ramping up to somewhere between 400 and 500. some plants may want more than 500, but don't go higher unless the plants beg you for it.
You should have a pH meter as well as a ppm/ec meter if you want to make sure that you don't let the pH get out of whack. Sadly, the cheap pH meters tend to die early. The Apera pH60 has been a great tool for me, still going strong after more than a year, and still within 0.02 of the calibration standard and it has never been calibrated. The cheapie I started with lasted about a week before dying.
The Root Farm nutes don't seem to have much micro nutrient content, it seems that the product depends on the medium to provide them. So, I would suggest adding a bit of kelp to your nute mix to help out with micro nutrients.
Good luck with your grow.
