Ok, so it's the 26th now - time for some more photos
I have had some problems with overfeeding - thought they cud handle the jump to a higher feed solution, but i was incorrect, so i moved it back down slightly. Also i had a small heat problem as i had guests over and had to keep the closet closed and the room closed to stop light escaping. You can clearly see these problems in the leaf.
Other than that i added some Co2 in amongst the canopy and ran some to the pedestal fan to blow straight over them. So even though they have had a set-back or 2 they have grown really well.
