yes the new more intense light allows your plants to grow at a faster rate thus requiring a small change in the nutes
adjust them slowly.
as for the ph being down quickly, the same applies
it sounds like you got everthing under control
keep up the good work
p.s.

that new light was a good choice, with the blue spectrum your plants should flourish in both veg and flowering stages.
again i say, good choice
