Plants were showing signs of a nitrogen diffeciency. I used 1tsp of Iron Green (8-0-0) with 700mL of water and they've gone right back to lucious green. Awaiting your comments. In a weeks time I'll have a hydro. Im hopefully going to purchase the HPS sooner then I thought and going to go ahead and start another grow in another closet doing hydro. Ive done some of my reading, but definatly have much much more to do. Your comments are widley accepted, so please dont be affraid to post.
