I had something very similar to this using the same soil. I flushed it several times over about a week. the spots stopped spreading and now they plant is doing pretty great. Next grow I plan on going with something without nutes already in it.ok i took a few pics, now it seems to have gotten darker, is it nute burn from the Miracle grow moisture control soil? or heat? the heat and humidity stays on average now 70-77 and humidity 50%
HELP!
