How Long till I crop my babys

Hi guys here's a little Vid as my cameras broken
The plants are 47 days into flower
1 X Liberty Haze
2 X Blue widow
1 X Northern lights Blue

They have been Grown in 40 L pots feed to waste in co-co / perlite
The wet dry cycle is around 4 Days under a single Fero LED System
I have been feeding them on GH 3 Part
with a range off additives from a UK company called Plant Magic
I am using around a 600 watt LED In a 4' by 4' tent
I also have a 100mm thermostatically controlled fan which runs at most times on the minimum setting
I took this video 2 days ago and today I fed them for what I think id the last time and will start flushing in about 4 days for a long 14 day flush :

what I was wondering is do you guys think I have gauged the timing right for the flush?

its been a while since I grew out a photo period crop as I have been playing around with autos for the last few years
any tips will be gladly taken on board

Well not anytime soon if there just baby's..

yo man nice plants, how dense are the buds? id say another 2 weeks yet... and i think their pronounced "trikes" not "tricks"...just saying haha
Deejay

lol its the accent country English
The buds are very dense
so your with me on the time line then bruv thats cool I think one of them may be a week longer who knows
and yeah lol I treat em better than my babys

anyone else ?

That'll be trichomes then, flush em dood theres plenty of nutes in those leaves for the plant to live on

yeah thats what I think I might do once they have a couple of days to dry out a little after this flush
hey tx guys if any one wants to see how they turn out come to my Liberty haze blog I have a couple of things on the go
cheers
Happy tokin cc
