I am growing an indoor AK-48 strain and noticed the first sign of cloudy trichomes. I want to harvest when most are cloudy to get more of a head high. I just dont know when I should switch to just plain water, and no fertilizer to flush out the fertilizer. Now? In a few days? Maybe weeks?
If it is a new strain for you I would suggest on the first harvest you let it go a little longer than your instincts tell you, just so you can see what happens. Then, at least you'll have a better idea next crop, and you can really pick the perfect moment. Beyond that, I don't know that anyone can give an accurate estimation based on the information we have. Good luck!
