This plant is 5 weeks old. It is grow in soil FFOF. I have used a half dose of duragrow veg 8 days ago and another yesterday. I have a 600watt MH light that is approx 26" from plant and temps in grow room are not peaking at 83-84f. What do you think? How should I remedy with minimal damage? Also, I sprayed neem oil which was diluted at 1/2 teaspoon to quart of RO water with one drop of dish soap but it was just before lights went off.
