Flos and MH may give you the right # of watts you need, but the spectrum is not correct. Yes, cabinet growers use 'daylight' cfls for flower but if you can afford a HPS go for it... it's most efficient.

Flushing was correct. I'd flush one more time, then give a weak feeding with a bloom nute (since you've got SO much nitrogen already, give it a week or so before feeding a grow nute again).
If you can safely repot into a larger pot with fresh soil and some extra perlite in the new dirt, that's another step to take to save the kiddos. But flushing was key.
