Well the last week the plant has started to show some amber trenchomes and as of today I'm seeing roughly 25% amber on the lower section of the plant. So today I start flushing. I know a lot of people say you don't have to flush but I disagree when it comes to hydro systems. Soil I get it trying to flush out all the nutrients is technically "impossible", I still do. But with hydro your plant has been directly absorbing the nutrients from the water with zero buffers like soil or coco and I find you can really taste it when you smoke it if you don't do a proper flush. I use the grotek final flush blueberry myself. The 500ml bottle I picked up a year ago when I did my blueberry has lasted a long time lol. My aerogarden grow box is going to be down for 2 weeks when this is done this grow. Got to make a few minor tweaks and then it'll be back up.
Happy growing everyone
