A question

So I decided to try out my 1st ever plant

I chopped off a piece and microwaved it dry. It's pretty good (surprisingly) and I'm thinking of chopping it down but I'd like to know if I should wait?

The hairs are about an overall of 20% light brown and the majority are white - Will I get stronger bud if I wait?

The hairs don't really tell the whole story. You need to examine the trichomes to determine peak harvest time. You want about a 50/50 mix of amber and milky trichomes, though that may be personal preferance. By the way, you need a 30-100x microscope to do this. You can get one at a hydro shop or ebay or even Radio Shack for less than $20.

And if you don't have the possibilities to buy a microscope just now, wait until at least over 50% of hairs have turned red. Best is to wait until more then 70% are red.

20.4 Harvesting Female Buds
The decision of when to harvest females can be simplified by understanding that you want to pick the buds after they have developed fully, but before degradation processes begin to lower potency. There are two criteria you can use to tell when the plants have reached full bloom. The first is recognising the rhythm, with which the plants are blooming. A second is the condition of the flowers as judged by the health of the stigmas and the colour of the resin.
Sinsemilla
Since sinsemilla flowers are not pollinated, the flowering period may last for many weeks. The most common rhythm for sinsemilla is that plants go through a stage of rapid bud formation, and the plants do indeed bloom. This bloom often lasts four to five weeks. The bloom ends when the rate at which new flowers form noticeably declines. At his time you should be able to sense that the bloom is completed. Buds are at their peak potency about one week after flower formation slows. This is the time to harvest. True, the plant may continue to grow slowly, but the main harvest is ready and should be taken.
With sinsemilla, some marijuana varieties have an extended bloom that may last more than two months. With this rhythm, the rate at which the buds form is drawn out, and progresses at a slower but steadier pace. The point at which the bloom is essentially over may not be as obvious as in the first case. Here, use the condition of the buds to make your decision. Stigmas wither first at the base of the buds (older flowers). Those stigmas at the top of the buds (younger) will still be white and healthy, although their tips are often brown. Harvest the plants when about half the stigmas in the buds have withered. The coating of resin glands should still be clear or white, with only a few golden or browned gland heads.
A third type of flowering rhythm is sometimes seen on plants from Thai seed. Flower buds bloom and ripen at different times. These plants also have an extended flowering stage that can last for over two months. You may choose to harvest individual buds, colas, or branches as they ripen.
