Ok the one in the middle is the white widowXBig Bud. The one on the left is snowryder and the right is BCN diesel. Have had 1/4 there nutes. and on 18/6 light schedule with a 315 watt multi spectrum. One tube style in middle and 2 spirals. Have veg and flower lights. Using water from my tap. right at about 5.8. Again i have access to R/O water but no one has commented back to me and let me know if i should change. But from what i've read, it's stuiped for me to change something that is working. I am only using 3 out of my 6 holes because i wanted more room. I know i'm gonna have to make adjustments differently seens as how i have 2 auto flowering strains in with the normal. and they are all feminised. I will be changing the water tomorrow and adding a little more nutes, slowly but surely is a good grow rule i've been following and to remember it's better to under do things than to over do! The nutes are just regular SH fire and forget style. I don't know much about nutes but according to mr. ed rosenthal they will grow just fine. I think i remembered to include everything. if you have questions and comments please just let me know. I will take anything i can get. knowledge hungry when it comes to growing.
