There are plenty...

First time growers frequently:
Overwater their medium based plants. When you pot your
plant, judge its weight dry by hefting. Then, water the plant
thoroughly, until water runs through the drain holes. Heft it again.
When your pot feels as nearly as light as it did dry, its time to water
Overfeed their plants. As MrSoul says, beginners rarely
under do anything. When all else fails, follow the directions on the
fertilizer bottle. [Editor's note: dont follow GH's instructions! Use @
1/4 their recommended strength, or follow recipes in the FAQ]
Overanalyze their grow. A first grow is like a first born
child: you pay attention to every little thing that happens. Further,
you worry at the first sign something may be wrong. Pay attention to
what happens in your grow, but do not try and find a remedy for every
yellow leaf. Frequently, the remedy of flushing your medium causes more
problems than it solves. Be responsive when things go wrong, but be
conservative in your remedies.
Overspend on grow supplies. New growers frequently commit
themselves to unrealistic and expensive first grows. It is much more
efficient to learn to grow and then invest in high end equipment rather
than the other way around. Most experienced growers don't have room for
all of the grow paraphernalia they aren't using. As you will see
throughout this FAQ: K-I-S-S.
Overpost. Try the search engine first. Chances are good that any question you can think of has been asked and answered before.
Talk about their grow. Don't tell anybody that does not have to know. How can you expect anybody else to keep a secret that you cannot.

1. Don't Overwater Overwatering kills marijuana plants. Water once the top few inches of the soil dries out.
Hydroponics is harder to over-water than soil, due to the abundance of water roots.
2. Don't Tell People Why? They will only be jealous. People love to feel important and
that is why they will tell other people; because others will listen to
them. Keep it to yourself.
3. Touch/kill Germinating Seeds It can take up to 10 days for a seed to sprout. The paper towel
method is not recommended because you must handle the seeds when
transferring them from the paper towel to your growing medium.
4. Grow seeds from seeded marijuana (hermaphrodite seeds) Unless you are prepared for possible disappointments don’t use "unknown" seeds. This is why people buy seeds from seedbanks.
Self-seeding MJ is produced from hermaphrodite plants or a very
stunted and late flowering male the grower did not notice. Flowered
hermi seeds will produce tall late flowering females coupled with early
5. Don't Over-fertilize Fertilize after first 2 spiked leaves appear.
Start with 25% of recommended label strengths and work your way up.
If the leaves suddenly twist or fold under, Leach and Spray with pure
water for several days!
Don’t fertilize your plants every time you water! (Soil)
A common watering schedule is to fertilize at full strength, then
water at half or quarter strength. This prevents excess salt buildup,
leaf and root burn. In addition, don’t water at full strength if the
medium is too dry – root burn can occur.
As a precaution, leach the plants with lots of pure water every 2-4 weeks.
6. Don't Under-fertilize Under-fertilizing is less common. If you prefer to give the plant
‘just enough nutrients’, use a organic soil mixture with blood meal and
bone meal or some slow release fertilizer with micro nutrients.
7. Don't Start with Clones Start with seeds. Bugs are a pain, as are plant diseases. Many
growers are able to grow indoors without pest problems for years.
Another grower’s cuttings are almost guaranteed to have diseases
8. Don't Provide A Bad Environment Always provide air circulation and fresh air even during the night
cycle. All the air indoors should be replaced every 5-10 minutes. Humidity between 30-70% temp aim for around 75-85' Even seedlings need a gentle fan to strengthen the stems.
9. Don't Harvest Too Early 25% of the weight will form in the last 2 weeks. Begin flushing
with 100% pH’d water when the pistil are 25% brown. Harvest when the
plants have totally stopped growing and the white pistils are at least
*NOTE: Outdoors if security is a factor make your own call on when
to sacrifice the fields. Also take buds continuously in case of
Q. Can marijuana grow in a northern climate? Marijuana plants can grow anywhere corn can grow. All it needs is three growing months - seed to harvest. 2 if started indoors!
Q. Why do I have to buy seeds? Why can't I use my own that I picked from my own stash? Most people desire, and want to be guaranteed, certain
characteristics in their mature female plants. The seeds from any weed
will all grow into something different. This is unprofitable and
inefficient. As opposed to knowing the single set of requirements for
your entire crop, you must provide a different set of requirements for
each of your plants.
Q. What is better for a new grower - hydroponics or soil? I believe the all around "better", more convenient setup is soil.
Hydro makes plants grow faster, but won't make your buds more potent
than soil. Hydro should be attempted after you have a few successful
soil crops under your belt.
If you are starting from seed and growing for personal, soil is the
practical growing medium. If the crop is started with clones and is
commercial, a hydroponics setup is more practical.
Q. Why are my seedlings stretching? Low light conditions. They also need a gentle wind. Plants will also stretch when subjected to conditions of high humidity.
Q. What kind of lights should I use? Cheap 4 ft. cool white fluorescent tubes : for germination/seedlings
400 watt Metal halide/HPS : for personal home growers
1000 watt Metal halide/HPS : for some personal growers and commercial growers.
*Use at least 40 watts per sq. foot of grow space.
Q. How far should the lights be from the plants?
Fluorescent: tips of leaves almost touching bulbs
400 watt halide : two feet away from seedlings and one foot away from grown plants
1000 watt halide: four feet away from seedlings and two feet away from grown plants
Q. How often should you water? Once a week or once every two week for soil and twice a day with a hydroponic flood and drain system.
*When top 2 inches of the soil dry out.* Occasionally provide periods of extra dry and wet soil.
*Allow 10% extra water to drain out of the bottom of the tray.* This will prevent toxic fertilizer build up.
Q. How long do your seeds last? What's the best way to keep them? Seeds can last over 5 years if kept cool and dry. They may last up to 10 years if sealed and frozen, but fewer will germinate.
