water Nutrients flushing

So I just got a new t5 8bulb 4' veg light and I wanna grab my clones tomorrow... I have found out that I need to water on average every 3 days and to use 1/3 gallon of water with a ph of 6.5. Next I am wondering how often do I feed these plants food and nutrients and what ones would you reccomend. I am using a soil medium btw....
Just not sure what nutes I need to get and how often to feed each different solution, and dont even know what the deal is with flushing. A lot of people here with a lot of questions. Hoping someone can enlighten me a lil bit here. thanks guys...
also is it necessary for me to buy a ppm meter? and a hydrometer. I know i need the ph meter but reading tonight I started reading about the ppm.. Gettin confusing guys but not discouraged yet....... any help would be dope, again thanks.........

fert every water unless they are unhealthy, only water as needed to keep slightly damp not wet small ones dont need water as much and it depends on heat and air flow as well you dont need any other testers yet just check the ph i think 6.5 to 6.8... get ferts for the age as well seedlings are sensative untill well rooted...fox farm and advanced nutrents are good

good looking 4dub thanks... anyone elses input is greatly appreciated as well..........

i think you might have to water more often than every 3 days, it all depends really. Just dig down in the soil a few inches if its lookin dry it needs water. Also it depends how big ur pot is regarding on how much water to give it....I nute feed every other day most of the time, Nute feed then water then nute ect..you could get away with water, water, nute if you wanted to go a little cheaper route....I use botanicare pure blend pro, liquid karma and bloombastic, bloombastic is pretty expensive you can use botanicare hydroplex instead on bbastic....

fuck a ppm meter just use the suggested ML per gallon on the bottle at 1/2 strength and work ur way up to full str if ur plants are liking it.....
i would also brew some tea like this except use blackstrap unsolfered mollasses instead of the honey shit....http://www.youtube.com/watch?v=H3WEwlMUVWg

to flush just give ur plants only water everyday to flush all the nutes out of the soil, you could also use some kind of flushing shit if you wanted to but water will be fine..just flush for a full 8 days or so with as much water as your plants will take without wilting.....

i use the botanicare nutes cause they are easy to use, fairly priced and ive got good results from them so far..and they are pretty natural, not 100% organic but made up of alot of organic and natural shit.....
