PH Maddness!!!

mornin to all members
luv the site and very impressed with all the years of experience on the forum. this is my first grow and first post. I decided to WASTE money and use around-the-way seeds just to learn what I'm doing.
my e&b system holds 10 seedlings in there 12th day. with 4 4' cool fluorescent light and half strength nuts. my problem is with ph levels. using mineral water i still had to adjust the ph with vinegar and Iâ??m watering twice a day. since this is my first grow Iâ??m very infatuated and always testing, the only testing equipment I have so far is my ph testing solution. every morning before my first feed of the day I check the ph level and everyday THE PH RISE from est. 6.0 from the previous day to around 7.5. I have done a lot of reading on this site and others but have not found anyone say they have to adjust the ph everyday. What can be my problem.

Well with 12 day old seedlings...exactly how much is "half strength nutes?" At that age they really don't need ANY nutes so perhaps you are burning them (overnuting) and that's what's causing the high ph. Just a guess on my part but I like it....

Try straight ph'd water on them and see if it helps correct the issue.

good luck. :)

No nutes yet
If you are doing ebb and flow, why don't you atart your seedlings in rapidrooter or rockwool plugs, and hand water them in trays, not in the system, until thye are solidly vegging?
Ebb and flow is a really easy way to grow, but tend your seedlings by hand for a couple weeks, until they are strong enough to sit in hydroton.

thanx a lot stinky and hound. will post pics 2morrow cuz plants seem to be healthy with a root system showing but will still try no nutes for a week or so. but please check for my pics 2morrow I would luv your opinion

Since you are using mineral water, it's probably safe to say that the minerals in the water are buffering the pH up. You don't want to use mineral water. Try using tap water and, if that doesn't work, use r/o water - but not mineral or distilled or carbonated or anything fancy, just plain H2O.

And, if want to be real dro, you need to start checking and, if necessary adjusting, your pH 2-3 times per day at least. Really, screw that light-weight infatuation crap, we're talking nothing less than obsession here.

...and as long as you're adjusting the pH, you might as well try to get it to the correct level, which is right about 5.7

Enjoy your grow. :thumbsup:
