Thank you Rusty.

The peat moss soil (at least the latest transplant) is only about a month old so I guess I can hope that the buffer agent is still active and will also hope that ph is ok since it is going in at the correct level.

Do you have any other ideas on why the plants look sad? I will switch up the water/fert schedule to half strength twice per week and see if that helps. They could be root bound again I guess. Is transplanting now a bad idea? They have about 4-5 weeks left of flower (estimate). They are in 3 gallon now and all under 3 feet so I figured they would make it ok. Is it ok to let them get root bound now or will it still affect yield and growth. When do roots slow down to concentrate on bud growth?

Are the bottom leave problems due to just being on the bottom and not really having an effect on the plant. Possibly just low light down there and old leaves moving on?
