Thanks for stopping in guys.

The plants are all between 25 inches and 36 inches. The yellowing in the leaves I've had for some time but I think I have narrowed it down for the most part to a magnesium deficiency. My water is pretty hard starts at about 7.5ph and 220ppm(my first grow was hydro). I guess hard water has a lot of calcium and can lock out mag. In the last few days I foliar feed epsom salt and water and it appears to have stopped it in its tracks. Yet I still think they are lacking a little Nitrogen, but I'm just going to let them ride it out at this point.

I've polinated the very tall one you can see in the pics thats most effected by the yellowing. I hope to get maybe 50 to 100 seeds to last me some grows for awhile. I would really like to get this strain down to a science.
