I used good amount of nutes filling the bucket with 3.5 gall of water ph5.5 , I'm transplants from my smaller rooted clone cubes. I want to use the remaining water on my mother plants? Is that a bad idea?. Also I'm going to wait 3 days before I put the big 6 inch cubes in deep water... About half way deep in water with an air pump at the bottom. Without nets or hydroton just big ass rockwool cubes sitting in water lol.. Little expirement since I grow in ff soil.

If all you did was soak new, unused cubes in it, I would PH and use it on my plant, yes. What are you going to hurt? In the future, soak your cubes in plain 5.5 water for 30 minutes, then flush with water with weak nutrients at 5.5 ph. The flush water has the nutes and can be used over and over to flush pre-soaked cubes. No sense n mixing up 3.5 gallons of nutrients to soak cubes.
