Dont forget the MDs can eat a lot of nutes....They are heavy eaters!!! Its perfectly normal to feed them some "N" during Flowering I have done it with all my MDs. After week 4 start cutting it out, your MDs have the Sour D pheno so it will probably be a 10 to 11 week flowering time! Your doing great!!! Keep up the good work and stay busy my friend....We need to start figuring out if and when I am going to make a trip out there. Do you know the estimated day of harvest for most your strains?
Peace
