The nutes will due fine, what your problem is is you need a TDS meter, and then all you do is listen to your plant! I'll cover how in a minute.
You said your using rockwool cubes, did you pre-treat them in europonic rockwool conditioner, if not this is your first problem. Like was stated just let the seeds sink don't leave them in the water until the tap root comes out. Everything else sounded good. What type of light(s) are you using and what are your temps including the temp of the nutrient.
LISTENING TO YOUR PLANT, chimera's feed guide to hydro growing.
Start your nutrient off at 150-200. After that take daily readings and if the ppm's drops 25 points then raise your overall nute level 50 points above the previous reading. If it goes up 25 points lower 100 points below what your previous reading was. Last through the feed chart away as for the most part those chart were not meant for MJ. One final tip, epsom salt, a teaspoon per 10 gals of nute every time you change it, which should follow the following schedule, cahnge initial nutes after 14 days, thereafter every 7 days!
