Also do you anything about re vegging I'm outdoor and might started not to early i started about 1.5 month ago plant boot 2ft but noticed it started preflowering we are now in 13.5 hrs of sunlight will they go back to re veg ...in az we were about 12 .5 hrs instill last week
I'm in SoCal, so I'm roughly at the same latitude as you. Yes, your plants will re-veg. If the days are getting longer and the amount of light is around 14 hours or more, they should respond by vegging. If you have no problem with that, you can let it veg all summer and it will begin flowering some time in July/August when it's getting less than 14 hrs and the days are geting shorter.
If you want it to flower, you can take it inside somewhere dark where it isn't insanely hot when it reaches 12 hrs of day, and bring it back outside at night. Using Phoenix as an example:

Daylight begins 5:32 am, so if you take the plant inside at around 5:30 pm and bring it back out some time after 8:00 when it's dark outside, it will continue flowering and finish its life cycle. I'm doing something similar with plants that are larger and outdoors where I cover them with gigantic contractor bags and then take them off a couple hours later.
As for fertilizers, if you want something that's really easy and inexpensive, I've heard good things about One Shot from Oregon's Only. They're time-release fertilizer granules you can mix into the soil that are supposed to last 3-6 months and it's about $15 for a 4-pound bag (I actually just bought a 25-lb bag for ~$60). It's got feather meal, bone meal, kelp extract, kelp meal, limestone, azomyte, worm castings, alfalfa meal, mycorrhizae, soybean meal, humic acid, organic iron, bound together with molasses and calcium lignin. I looked at the metals analysis , which is attached, and while it's not below detection for all analytes, it's low and the application rate is extremely low (two tablespoons per gallon of soil every 3-6 months) so it should be safe.
I have heard people say that a PK booster is useful as the plant transitions to flowering, which stands to reason since it's a 3-10-0. There are many different bloom boosters on the market; Koolbloom by general hydroponics/biobud by general organic, Big Bud by advanced nutrients, Resinator by rock nutrients, etc. Which one works for you will depend on how much you need and your price point.
