<span class="link_user">@Ramman</span>, my crudely worded inexperienced guess (sorry): put the light at the ceiling of the tent that way the plant can grow into the light instead of fighting it. also, 831 ppm seems high to me, better to be deficient than toxic. Be careful about overwatering(week 4 puffy, sulking leaves). Feel free to chime in more experienced growers. Looks good so far, I'm interested to see how this goes.
