pagrdnr, are the ones that are staying tiny having a mite problem? I wouldn't fertilize until you can sent them outside?

No, no mite problem just no growh. I'm just wondeing if I should try to give those leaves a boost with a little fretilizer. I am talking about where the big outdoor leaves fall off and there is a circle where you can tell there was once a leaf and then new leaves start growing from just above it. These leaves have stayed relly tiny for weeks now, and I'm wondering if a bit of diluted fert. will coax them out of hiding, lol

karma is right first check to make sure you don't have mites. Small curly distorted leaves are a sign of broad mites. Search the threads there is a lot of recent discussion on this :)
Also make sure your cuttings are getting a good amount of light.

As far as fertilizing cuttings, I would not do it until you have a pot of roots on the cutting. If you do not have any mites and want to do something for your cuttings you could try some spray n grow (without the bill's perfect fertilizer added)and spray lightly on the leaves. I have used this on all kinds of cuttings and they all seem to love it. It is not a fertilizer but micro-nutrients. Always make sure the plants are well watered first before using anything on their leaves etc.

IMHO...That being said...LOL Depends on what you want.. I use ST and seaweed each time I water.. For z5 without perfect conditions I think it is to early...

I don't start fertilizing until it's just about time for them to go outside 24/7 but I do occasionally give rooted cuttings and older seedlings some ST, kelp extract or a bit of diluted compost tea when I water them while they are inside.
