Ok..Mother in Rockwool Mini Cubes!

Ok...i'm talking about mini grow cubes not 1" no 4" cubes. This is a feeding question...I've grown two mothers in this stuff but doing it all on a whim. Now I'm on another set of clones turning into mothers and I don't know a good feeding schedule for minicubes. Does anyone and I very much doubt it grow their mothers in rockwool minicubes????? Whats your feeding schedule? I'm going with bonsai mother technique and I need to know how to feed her. Help plus +reps

I would just use a light veg formula every water then when you are ready to take cuttings back off on the N alltogether. N slows rooting. Like a clean res. Maybe if yu are brave thro in some P! That helps rooting.Oh yeah, I used those mini cubes to root cutting in net pots then into dwc. I used a reg veg form then. I like the cubes, later i ripped a few experimental babes up for room and the way the roots had bonded to the cubes was amzing. Very cool thing. Fast growth also ebb and flow with those I was just remembering. At this one hydro store I just found yu can buy 25 pouds of rockwool not cut or formed, just as a big bag! Cool.
