I watered them with more bloom nute's a week ago,, today I started the flush,, I used a 1/4 tsp. Of Epsom salt and 1/4 of molasses per gallon,, this is the preflush,, the next watering will be plain water,, then the next with Epsom and water, then water again,, the epsom helps flush salt build up in the root zone,, I didnt use hardly any nutes during this grow so salt build up isn't a big concern for me,, but I'm playing it safe,
