Whats the ph of the tap water your using. 30% is real low from what I read around 50-60% for vegging. You should get some regular/blank potting soil and some perlite for drainage. The ph of your water should be somewhere between 6.3-6.8. Well thats what I keep mine at. You should also get some nutrients because your going to need them.
