I currently have some clones in 1.5" rockwool cubes that are showing roots. I plan to transplant them into 6" grodan cubes shortly.

Grodan recommends soaking the cubes in a solution with a pH of 5.5 and a feed strength of 1.5 EC (750ppm). This seems WAY too strong for newly rooted clones (currently being fed at 375ppm).

Has anyone gone that strong right out of the gate? Any issues? Should I increase my feed strength on my small cubes first before transplant?

Any advice appreciated.
