Yellowing rose leaves

I took 4 rose cuttings about 3 months ago and they have been growing quite well. They are in 2 pots stood on a layer of gravel, in my shed in the (open 2”) window (so that they don’t get too much rain.) The compost is damp - not wet. I did put them outside during the day when it was sunny - but not for a week or two. 
Some of the leaves are turning yellow - one or two have slight blackspot but not all. I sprayed them with Rose Clear a couple of weeks ago.
Is this a deficiency?  I have plant food for containers and also tomato feed. Would this be suitable?
Photo of pot was taken in October.

    It’s probably just seasonal leaf fall 🍂

    I did wonder. Presumably they won’t need feeding until spring?

    I’d leave them in a quiet and sheltered corner of the terrace until spring. Nothing to do until they wake up in spring ... March-ish 😊

    I put them in the shed as we are getting so much rain. I don’t have any trees (apart from a large Hebe) so finding shelter is a problem. I suppose I could concoct some sort of cover.

    I’d simply put them against a house wall in the lee of the prevailing wind. Just make sure the pots are raised if the ground so they can drain freely and they’ll be fine outside. Personally I wouldn’t keep them in a shed.

    Sound advice from Dove.

    Rhis yellowing of leaves doesn't only affect roses.  In nature, and as the autumnal period takes over.  Deciduose plants cease rhe growing season and so such natural processes tend to decline.  Photosynthesis slows down and stops.  The action of sunlight and tha ptoduction of sugars and other life sustaing processes slowly shuts down.  If this faielrd to take place.  The moleculat make up of the plant would fuse and blow out.  Simple terms.  The leaves slowly react, an shut down.  The biological joining of the leaves to the plant stem, close and become sealed.  The leaves wither and fall.  The host plant has seale ditself, now awaing the the call of spring and rejuvination.  Hope this helps.
