***BIG bang vegging...and purple wreck + mystery in flowering when r they ready?***

I have some pics of my grow.

the small plants in orange pots (buckets from homedepot with holes i drilled in...$2 a piece...beats $10 per pot) are 6 big bang fem seeds i got online.

the two flowering plants are a mystery seed i found in my stash awhile back (not sure what it is...some type of sativa or sativa dominant plant...its 3 ft tall) and a fem purple wreck i bought...

flowering began march 31st for both. the sativa mystery plant is 3 ft tall and the fem purple wreck is 2 ft tall.

flowering under 600w digital hps. fox farm ocean forest soil with fox farm grow big and bloom nutes. ph is stable. according to the calender they have just over 2 weeks to go.

how long before (good guess) they are ready? should i flush now (meaning does it appear they will be ready in two weeks)?

thank you.
