I haven't been here for a while as I have been undergoing the same problems I related to you all during my previous grows which after a little thought has now been resolved.
During my previous grows there was some signs of cal/mag deficiency during the latter stages of the flowering period. There would be significant plant stretch and leaves would pale and mottle with cal/mg deficiency. This would prevent the plant from maturing and finishing off and would in fact revert the plant back to an almost veg state of flowering.
After looking at the way I grow and what I am doing, I have found that I have not been changing enough of the water in my reservoir. The reason for this being that I dont really like throwing nutes away. Anyway, after some consideration I have found that if I change the 40%+ of the water during each feed (I do this over a period of two days where I remove 5-10ltrs each time and refill with the same/extra).
The practice seems to be that one should change all the water regularly. I will try to change a significant amount of the water once a week/fortnight in future. This will prevent the problems that I have been encountering. So after my hurdle (which has taken me on quite a nice little journey of learning) I guess I should show you guys some pics.
The Crop 6-4-2014.jpgThe crop 2 6-4-2014.jpg
I have no idea how much there is yet.
Some things to see is the airy N Lights bud on the left of the first pic. This was due to it fighting with another plant in the same tube. I did not space them far enough apart. I think about 50cm of the tube can be dedicated to a single plant. I am growing a single plant in each tube for my next grow (Amnesia/N Lights).
Another thing is to see the S Skunk on the right of the second pic which had the classic cal/mg problem I was having and it was suffering a lot. You can see that I have managed to make it bud like it should and it will give a nice yield.

N Lights 2 6-4-2014.jpg
This is the second N Lights that was sharing the tube.
The attached image is that of the first N Lights in the portrait of the crop pic. As you can see there is quite a difference in the way the buds have formed on these two plants.
Hope you guys like the pics. You will see some nice plants and fewer problems next time. I will post some pics of the new ladies soon.
I would like to add that I have had a pure N Lights grow just before these pics which I didnt show but I got about 12oz or abour 320gms from the crop. A lot of the bud was very smokable and strong. I still have a little and many have enjoyed the sopoforic medication with great satisfaction.
I will see if I have any pics of that grow to show you.
