Plants are growing up to an inch per day.
This difference in growth is mostly due to genetics, but also probably due to early light availability. Should not be as much of a consideration going forward as the light has been upgraded to better suit the grow environment.
Moved front center Aurora to front right and moved back right K2 to front center. This will hopefully increase the growth of the K2 and slow the Aurora so plant heights will be more even. Also gives the Aurora an entire 1/3 of the tent to spread out.
Additional LST on the K2 to expose more new growth sites.
Re-evaluating the number of plants in a 2x4 tent.
During this week's water change I flipped the rig end-for-end. I now have access to the reservoir through the hole where the dead K2 was so I no longer have to lift the lid to drain/fill. For future grows, I will look into a better method of draining and filling. Maybe a port on the reservoir, waterfall system... something. I won't be able to lift that lid much longer due to plants growing rapidly. OK for this grow, though.
Also during the rearrange, I moved the big Aurora to the top left and did some additional LST and moved the K2 to top middle. Aurora now occupies twice the space of the other plants, but brought the overall height back down to match the others. I have a feeling it won't last and that this plant will be MASSIVE compared to the others.
