Hi , I'm currently in my second week of indoor growth, my plants are 14 days old. They used to be under 2 400w hps but I took one off yesterday as someone recommended on this site (I was starting to have problem with my temperature control anyway). Aside from some waving in the leafs they look healthy but yesterday I observed those little things on some of my plants , what do you think? I have 18 of them and the cotyledon are turning yellow on 2. They are currently at a stable 80 degree ,I use tap water but I have not yet tested the ph of my soil (2/3 peat moss/perlite pro mix mix and 1/3 sea compost).
