Don't follow the directions on the bottle you'll kill your babies more often than not. Hard to say knowing your medium etc but first advice- get a ppm meter and make sure you set the tds factor for your nute mix eg i use dutch master advance that uses a .5 tds factor but my ecopen comes with a setting of .71 from factory. Fixing this dropped my ppm reading a full 100 points so it's worth checking. I use rain water with a ppm of 40 and add canna rhizotonic at the 4ml per litre rate first, then equal small amounts of dutch master a+b until i read about 150 ppm above your base ppm, 40 in my case, and feed gently from week 2, my first feed is only one cup straight onto the rockwool cube i germinated in. In my case i use coco, which needs to be rinsed before use, never use straight water always use a tiny amount of a+b usually 100ppm including the base amount. Mj seeds should be fine off tap water for the first week, i like to use it due to the chlorine. But get a ppm meter! It's all guess work until then and remember to start on the low side of the ppm scale and work up, ph after adding all nutrients to about 5.5-6
