11 plant garden watering

[Kasey]

Hi Ron, About a week ago I built a 11 plant garden and when everything was going well. Until a couple days ago. I bought a timer from Wal-mart that is set up to water for 15 min on and 45 min off it was only $9. Every hour. Is that too much water for small plant?

Also I can not find a place that sells hydroponic nutrients. Does Wal-mart sell it or maybe I just can not find it?

I tested the ph today and it was above 7. Is this the reason the leaves are a little brown or is it too much water?

I have been using a nutrient that is made for soil because I can not find another one. Is that the reason why they are browning?

The ph was fine when I transplanted them to the hydroponic system, and five days later it was over 7. How often do you have to adjust the ph?

and what changes the ph so fast?

I appreciate all the help you have given me, the site is very interesting. Thanks.
