Those buds are nowhere near ready to come off buddy, the THC hasn't built up enough to get you where you want to be. I suggest buying enough to do you the now and just wait yours out.

Get a USB microscope, you seriously wont be sorry! I've played with mine for hours and it really comes in handy when it comes to pulling the plants. No more guess work! Look at the trichs! If you don't want to splurge for the USB Microscope(I promise, it's worth it), get yourself a loop magnifier. Back to your real question. YES, you can chop different buds at different times and let the lower ones mature longer. Edit: P.S. If you get a USB microscope, WE all get to see pics too!
