Help. How often should I or should I change my reservoir water.

How often should I or should I change my reservoir water. I need to know this because I plan on starting a crop of 6 plants this week. I'm a noob but i've been reading the threads, but I just can't seem to find the answer. Much help would be appreciated.

for medium to light feeding change it weekly, for heavy feeding change biweekly. If you've got the cash and want to do it the right way for sure, buy a ppm or tds meter and you can gauge how fast your plants are eating. Maybe even keep charts and do the same thing again because you'll have exactly the right amount for optimum growth and uptake.

Every 7 to 10 days is a fairly standard answer. Some also watch how much water they use to top up the res. each day. Once they "add back" the same amount as their res capacity, they do a full change.

Also I was thinking about using the General Hydroponics Flora Kit it includes FloraGro, FloraBloom, and FloraMicro. Also Mixing instructions are included. Would this be good for the whole entire growing process. or is it only good for the vegatative stage or the florwering stage.

GH 3 part, Micro,Grow and Bloom are perfect nutes to take you threw the hole grow.
Do you have a PH pen yet? Absolutly necessary IMO to have a good hydro grow and next would be a TDS pen.

No, I don't have a PH pen or a TDS pen yet but I wan't to go to home depot this week to get it. Do you know of any other stores that might be able to help me out, I live in philadelphia if that helps. Also i've heard that you can spray bug spray on your plant and it gets rid of bugs and boosts the thc levels, What do you think. Is there anyway to control or make your plant have a better probability of become a female instead of male. Oh yeah I have decide to let my first harvest let nature take its course and let the males pollenate the females, that way i'll have plenty of seed for my future harvest.

Bug Spray equals bad idea...!!! You can get PH test strips at Wal Mart, but I would whip the yellow pages out and find a garden/Hydro store and you will be in a candy store.
Dutch Masters has a femanising spray I believe and there is one other I herd about yesterday, if you are really going to get I can take the time to look it up, but if you are just going to let your plants seed then you probably dond't need to worry too much about it now.

Thanks for the advice i'll go to Wal-Mart tomarrow to get the ph test strips, but are they in like the gardening aisle or the pet stuff aisle. As for the femanising spray I believe that Dutch Masters is a site and your not talking about the dutch you rool up with so i'll google that. Don't worry about looking the other one up because your right I probably wouldn't even get it at this time. thanks. Since your helping me out I know you probably grow your own, so do you have any pictures of your crop.

Dutch Masters is a company that makes different products that many MJ growers use.
I will link you to a page or two of mine that I need to update, but you can get an idea of some of my stuff, but I will post back in a minute with the links. In the mean while here is a link that will show how to use the GH 3 part in order to maxamise your growing IMO, http://boards.cannabis.com/showthread.php?t=93676
It may seem confusing at first, but just ask any questions and read some of the questions that are posted throughout the thread and I think that you will get enough info to be able to ask some questions to get you on the right track.
Adieu

Like I said, need to update these threads, but these grows are some side grows not my main grows. I need to document a grow with my flower room full, but I am just messing around trying some different things right now.
