Well I have been checking this daily and have noticed that the EC has been creeping up, its now up to 5.0 (2500ppm) which would indicate that the plants are using more water than nutes, the PH is around 6.2 today but this has varied from around 5.8 to 6.5 over the same period, the plants are still looking great with no signs of burning, but I have noticed that the buds seem to filling out with nore leaf than pistills, some of the buds seem to look like a mass of little leaves as opposed to proper buds! I have checked sex and there are no Male flowers anywhere. this is the third grow of AK47, and I remember the buds last time seemed to get a bit leafy, but the first grow was in soil and the buds then where huge with allmost no leaf between the buds. The first pistils showed on Xmas eve so they are only about 3 weeks into flower, but 5 weeks from 12/12 if you know what I mean, I will post some pics later.
