How much longer on my Northern Lights grow before harvest or flush?

Hello everyone. I'm growing 12 Northern Lights plants from Nirvana under two 400 watt HPS and one 125 watt daylight cfl in my BCNL Producer grow box. The pictures below were taken today at day 55 of flowering. My trichome development seems to be around 5% amber colored with the rest a split between clear and cloudy (probably more cloudy). My res ppm is around 550 currently. Please tell me when you think these will be ready to begin a flush. I plan to flush for around 5 days with final phase. I'd be really thankful for some help...

Anyone have thoughts?

heyy man. i hink theyre looking great! right on track. i would wait about 5-7 more days before i would flush.. from that pic... you would be surprised just how much growth can happen in just 1 week! they look really really good tho!!

if u want sum more opinions... u could post a pic of it and ask wat ppl think on my other thread i got going.. its a thread dedicated to Nirvana fan/plants/experiences and what not. heres the link.

im sure some ppl will also give their opinions. =)

Plants are looking good. I would start flushing now, and in a week or ten days all the clear trychromes should be cloudy and a few more amber ones. Time to harvest.

peace

Great, thanks guys. I'll post some new pics on that thread later today chb.
