carjosanswered grow question 3 years ago seems its not solved but i have an idea, 2 were in the closet with the spots, i took out out to the grow room, nights are finally close to 20c in there now, that one was worse, but looking better, the remaining one in the closet now has burn marks. it could be the oxygen level i think,. I am deciding if i should reunite them in the grow room. its a difference of electric light at night and natural light. the first move was smooth, just took her in the living room after 6 hours light to adjust from HPS and after a couple hours into the grow room. now is six hours HPS shift, should I move her? is it oxygen level? the burns are way worse from 6 hours ago.
