Trichomes - When to flush - Harvest questions - With trichomes pictures

[madatakesi]

Hey guys this is my first grow ever i started with auto blueberry and they are in day 39 of flowering .
I'm currently using BioBizz Lightmix soil + Biobizz nutes and giving her each feed with 1ml Grow / 4ml Bloom / 4ml Topmax, i'm planning to go bigger because she shows no sign of nute burn and she seems to love it , i feed her when the top inch soil dries out . I'm growing her outdoor : When should i flush her / or harvest , the problem is i don't have a microscope so it's so hard to look at the trichomes to see if it's cloudy , clear or amber so hopefully i will get some helps here , here are some pictures :

I even edited the picture to see the trichomes better ( click to see the original picture )

Looks to me like you still have a lot of clear heads, you can zoom in on your picture and see that fairly clearly. Nice looking plant just seeing the main cola. I wouldn't flush yet, be patient, it's worth the wait to not harvest too soon.
