Hydro Fast Buds Crystal Meth

Starting off the third week and she's looking healthy, lots of new growth every day and roots are white as snow, had to spray some black stuff off the roots that was building up between the water line and the net pot most likely build up on the lower stones from the humbolts secret since it's thick on the black in the container. it all washed right off and the roots still look super white underneath so it's not a root issue at least. Update, switched over to bloom nutes and seems like my nitrogen toxicity issue has been resolved. looks like I should have read the labels and seen that sensi cal mag plus has 3% nitrogen in it so I should have reduced my high nitrogen grow nutes to compensate, will probably help during bloom phase to keep the leaves nice and green but was too much for it while using normal veg nutes.
