First grow - questions about nutes and watering

Hi im a beginner and this is my first grow, i have some questions if you can help


im going to grow some lowryder #2
40% organic wiggle worm casting
30% organic vermiculite
30% organcic perlite

my question is can i use just iguana grow and iguana bloom for nutes will that be enough?

and how much should i feed them , and do i feed them 1 time per week, and i read that you mix the nutes in sterile water , so i need 1 gallon of water and then put the nutes in, mix it and check ph levels? what should the ph level be?

and what products should i use to bring ph down and bring ph up if needed?


how much should i water, and do i water daily ?

i am going to use Floralux 400 W HPS growing light and HPS bulb

i bought some reflectors i will put up on the walls, the area will be about 3x3x12ft? not sure the height

it will be grown inside a closet and i will grow 3 of them, they are all female



thanks

or should i just use Roots Organics soil

can i mix some worm castings with this soil? would that work good?


the reason i ask is because i already bought some worm castings but i havent bought the perlite or vermiculite yet

so which would work best?


thanks

okay let me start of by saying you should always start off your feeding at half strength then move your way up. you need to either get water from a a place that sells it and make sure the use reverse osmosis or you can just put some faucet water in a 5 or 1 gallon bottle and leave the bottle cap off so the chlorine can leave, it takes 24 hours before it goes away.your ph should be between 6.4 -6.9 if your using soil as your medium. GH sell a ph up and down the even have a package that has both. thats what i use in a pinch you can use lemon juice to drop it. then for watering i would suggest adding half the amount of the size of the pot, so if you have a gallon pot use about a half gallon maybe even a little less. also only give them half the amount your going to then wait 15-20 min then add the rest. pick the pots up they should be heavy now just wait till the pots get light before watering again. and you can add the castings to the soil just add about 8 cups per bag maybe even add a little dolomite lime to neutralize the soil. if you have anymore questions pm me
