This is a question regarding PPM and top-offs:

Vegetative Setup
T5 Fluorescent
Drip Irrigation
18 Gallon Reservoir
18/6 Light Cycle
10 min. Feeds 3x Daily

Lets say I start off with PPM of 550; after 1 week it goes up to 800. I know to bring it down you simply add water. This is a "top-off," correct? How would I measure the amount of nutrients it needs? Will there be a time when the PPM goes down? Finally, as the plant grows it will need more nutrients per top off? Is there a set system for doing this or does it vary from strain to strain. Basically, is it something I will just have to experiment to find a good amount?

I have done quite a bit of reading on my own time and know the frustrations of people asking for handouts. This is one thing I couldn't find...

As you may have guessed this is my first time...Well, it will be my first time with all the information. My first attempt resulted in the massacre of 6 innocent Satori seeds...

Any information at all will be taken with gratitude as I hope to get the second attempt underway with all the info I need.
