hey weedhound...will follow your advice and see what happens then...was going to put them under 12/12 tomorrow, but i'll wait until wednesday...the veg nutes i use should (at least according to canna's own instructions) continue to be used in the flowering cycle until the first sign of flowering, so i won't be changing (or adding!) nutes at all in the next few days. if you'd like, i'll update with pics on wednesday....hopefully i can save these girls!

i've only done two other grows before this...also using nft...and there were simply no problems...the first was nirvana bubbleicious, the second was snow white...but those seeds weren't 'feminized'...are there generally more hiccups with feminized seeds in your (and other's) experience?

oh, and i almost forgot...the one plant that's all shrivelled up was topped after showing four sets of leaves...could this explain her extreme reaction to the uptake in nutes compared to the other plant?

apologies for having so many questions! i'm still a 'newbie' like they say...
all best,
jash
