I found these pics online and I'm wondering what the problem is. They're apparently 21 days old and started out fine. After about 7 days spotting appeared on the older leaves and started creeping all over. The person went to an "expert" at the hydro store and the expert figured it might be a mold and suggested a spray. ( I understand, snake oil and all that) From what I can tell they were sprayed thoroughly on day 14-15 and again on day 21. Any Ideas or input is welcome. oh, temp ranges 70-75 and RH is 40-50. pics to follow
