pineapple express suffering!!!

hi all,
I have recently moved and
lost Alto of equipment
including my nutes, my
pineapple express is flowering
and she is 6 weeks old, I am
not able to get nuts ATM
because every penny went
into moving, so I have been
looking threw a bit from the
old house and started using
fizzy ferts which has a npk of
15-15-15, n is very high, I
also have been adding meal
worm castings, it was all going
surprisingly well and now all
of a sudden some of the
stems of leaves have turned
purple and the bottom set of
leaves have turn yellow and
curling and around the plant
I am starting to see some
yellowing around the rest of
the plant, may I ask if
someone knows what this is,
and how I could fix this, she
is from my first cfl grow, I am
moving to hps setup after she
has finished, bit I'm not
about to give up on her now,
thanks
