Thanks for the replies!

So, I'm going to get Florakleen, Serenade, and a dehumidifier this week!

I agree about the salt buildup in the rockwool... I can see white crusty things on the rockwool and so maybe if I pour RO water through the RW enough until it goes away? I will also do a system flush. Does that mean that when doing a system flush with florakleen the girls don't get any nutes? Wouldn't that increase the def and thus the yellowing? I have the thread about flushing w/ florakleen before harvest bookmarked, should I follow it?

I will also raise the lights and LST the high leaves so they're farther away.

Thanks for the replies!

I got 12 grams for $40 tonight, so I'm happy
