Looks to be coming in allright, has about the same development as the White Fire 43 growing alongside it, at just a bit more than half the size. The seeds were advertised as being short plants, so I suppose it is right where it should be.
Day 43: Seeing what could be either nitrogen or phosphorus deficiency setting in on a few leaves. I would guess it would be nitrogen as it has just switched over to bloom nutrients and they have a large drop off in nitrogen content. I am going to start using grow base nutrients along with bloom nutrients during flower cycle to keep the nitrogen levels consistent.
Also, I am not sure the plant is not receiving light burn, as the tops of certain canopy leaves are slightly discoloring right at the tops. I raised the light and adjusted it as to where it is no longer getting the intensity it was. The lighting change along with the nutrient boost should hopefully take care of the issue and get the leaves a nice dark green.
