Nice one for updating m8. Glad you got your nutes now, hopefully it will all be plain sailing from now on.

Have you added the extra 125w cfl into the grow room yet? You are going to need it, with all those plants.

As for the the second pic of dots/yellowing of leaves, I'm not 100% sure but I think that this is caused by over watering, is it on the old fans near the bottom of the plant? How often are you watering btw?
