So I am 4 weeks into my first grow and so far so good. I have 3 strains...Arm Skunk, Blockhead and Buddahs Sister. I started clones in 4" rockwool cubes and growth has been great for the most part except for one single plant of the buddas sister strain. Several of the same strain have doubled in size in less than a week (lovin it). Yet this one (named her Gertrude) just seems to not want to progress as much. She does have a couple new leaves coming in and I can see roots coming out the bottom (white and looking healthy so thats a good sign). I just transplanted into 9" netted baskets w/ loose rockwool today so I'm hoping that will help kick her in gear. No leaf discoloration, drooping, yellowing....ph is good, keeping nutes at 700ppm for now increasing every week. One thing on this particular one is a green algae looking color forming on the top of the 4" cube. I've been hand watering up to this point so I dont think overwatering is an issue. Any thoughts, ideas, same thing happened to be stories would be most helpful. Again this is my first go at it...
