One of the most common questions asked by novice growers is “What should my plants look like at x days/weeks old?”
Naturally, anyone putting their time and effort into a project wants to have a point of reference against which to judge their own progress (or that of their pants, in this case). The answer is:
Plants will vary in size and appearance depending on a variety of factors: Genetics, soil, lighting, nutrients, temperature, handling, and the elusive “green thumb” factor. As you can imagine, a plant growing outdoors under full sun in June (northern hemisphere) will be a lot bigger at 2 weeks old than a plant growing in a converted computer case running 50 watts of lighting!
In any case, cannabis plants do tend to develop certain physical characteristics at certain times in their life span (first true leaves after 3 – 4 days, alternating nodes after 30+ days of vegetative growth, calyxes and pistils after a week of flowering light schedule, for example). Barring any problems, after two weeks of vegetative growth, you can expect to see a plant with several sets of leaves, and are likely to be able to smell that characteristic “mary jane” smell on your fingers after gently rubbing the leaves.
Don’t be surprised if your plants leaves alternate between “reaching up” towards the light and “sloping downwards” towards the ground – this is normal. Leaf color will range from an intense, deep green to a light yellow-green or “lime” color. What isn’t normal is yellow leaves with stunted-looking new growth, patches of brown or browned edges, dark spots or a mottled look to the leaves, or leaves curling up into a sort of “taco” shape.
Here are some shots from our current 100 Watt CFL grow. A two-week old Dinafem Critical + plant. She’s (yes, “she” – this is the only feminized seed in this grow) looking quite healthy and of good size for the humble 100Watt grow. She’s ready for transplantation into the larger final grow pot.
