Yeah, I like 60-70 for veg.. I try keep in 40's flowering If I can but some strains don't like going under 50.. I read that about sour diesels night before I found mine had, wish I read it the night before I put her into flower look for other herms with your genetics, might be an indicator.. She also might have just got mixed up for a night and has reverted back once the balls were removed.
