Soil is alright at that but 6.5 is better from what I have tried. Also I am not sure if you should try to balance anything with the peat pucks after what you added, if it was me I would transplant in some seed starter mix of sorts (whatever you like) and then from there just water with ph'd water like distilled with cal mag for example or your water sounded like it wasn't that bad. Things will move on and they will get tough as nails in no time. I myself wait till about four nodes before any nutes but that varies with strain and many other factors but two weeks old or four nodes is a safe bet. Others will chime in, lots of helpful people here.:hippy:
