Hey guys, this is my second grow and I'm at a loss for words on these spots, My plants are under 1 400w light about 6-7 inches away from plants. Foxfarm Ocean, i use no nutes, Just water when it's needed, with Poland spring distilled water, this partiular plant is 5 months in and in its budding stage, These spots started on the top section of my maine plant, The other 6 plants have no signs of sickness. Opinons and advice would be greatly appriciated! If you need more info just ask! Thanks everyone. I guess all I want to know is how to fix this problem,.
