Wtf? No way. Do not harvest now or you'll be sorry. Premature bud is the worst, tastes like shit and gives you a headache. Plus they can double their size in the last 2-3 weeks so you lose tons of bud weight. Patience my friend. Wait 2-3 weeks and you WILL NOT be sorry.
Also, forget about flushing. It's a fucking myth. Why would you starve your plant when he needs it the most to produce that final heavenly goodness? Think about it.
