Dendros just sulking

[AHAB]

I have to chime in here...
I have quite a few dendro's in S/H and they are growing very well lot of roots and the new growths are 2-3 times the diameter of the older canes. So I know they are absolutely loving it. I use MSU @125 ppm N.I use KLN and Superthrive once in awhile but that is pretty much it.
Please give it another look and see if some other parameter is not up to par, maybe needs more light, cold weather to set buds... could be many things.
For me S/H is a very easy and very clean way to grow plants.
