Harvest?Well that truly depends onwhat the trics look like and what kind of medication your trying to aquire.If your not certain which,well a standard rule is around 20-30% amber trics across the entire plant.But some(Me included) will do an all cloudy with maybe 2-5% amber if that.Some will even do all cloudy with a few clear too.It all depends on what yout trying to achieve my brother.But in the pic it looks like its either got something goin on or its been feeding on itslef if you have flushed it well.If the latter is the case and the trics are atleast all cloudy,I would harvest.But I cant see it all that well.I hope that helps you decide.Happy harvesting my friend!!
