overfeeding plants in hydro systems. Over time you will get to know
your strain and what it likes. The better you know your strain the
better you will be able to control your feeding amounts.
HARD WATER PROBLEMS
If you have scales in your bucket or what looks like kettle rust
then you have not been maintaining your pH level. Scale is caused by
very acidic pH levels. Your local water company will provide you with
a read out of your water. You can buy nutrient products to use with
hard water. If this problem persists just drain and clean your reservoir
and mix a new batch of nutrients to the correct pH level. Some use a
Reverse Osmosis water filtering system to clean their tap water.
Distilled water has a stable pH level of 7.0.
HOW TO KNOW WHEN TO ADD MORE NUTRIENTS
This is easy and not so easy. Beginners rely on a ppm meter,
but a veteran grower learns to read the plant. The plant will tell you if
is getting enough or too much or too little. It takes a few grows to learn
to read the plant but you can do it with experience. The plant may
have drunk all the nutrients up or just some of them. Some nutrients
are taken up by the plant and stored within the plant until it needs
more. A top up can be done if you do not want to change the reservoir
totally. If you do not have a PPM meter to calculate this accurately,
