Thanks TeKdc911.
Today I took it out of the tent and removed all yellow leaves, as at this point they are only shadowing the healthy leaves.
I also took the WW out and noticed some yellowing on the lower leaves and a couple of brown spots. A couple of small leaves from bellow the canopy were all yellow, no spots.
Posted some pics in my thread.
