700ppm?!?!?!?!? thats way to much! I would recommend a number between 150-250ppm
It took me i think 2 weeks until the roots really entered my res.
125Watt is more than enough at this stage! Check the ppm of your tap water if its too high you might consider to get a cheap RO System of ebay.
ps.
You questioned when to feed bloom nutes:
You switch to bloom nutes when your vertical growth has come to an end and flowers are developing.
pps.
I for example just have a ppm of 640.
