I have some Purple Kush Plants that are at week 7 Pyramid says 8 weeks from germination but all my trichomes are cloudy. Also there is not a single pistil that has browned they are still white. Should I wait the 8 weeks or harvest now? The top colas look like the pistils are shriveling up and the side buds look like they may still have some maturing to do. Maybe I should take the top colas and let the rest go til the 8 weeks are up? Im not sure what to do. Harvest now? wait 8 weeks or a partial harvest now and finish at 8 weeks. Any advice or help would be greatly appreciated. Thanks in advance
