B, Only if it gets larger, IMO, as it might heal itself (an optimistic view, I must admit), but you want to make sure you have a clean, sharp knife, some isopropyl alcohol (75% is fine, to spray the knife as you cut / at the end of cutting) and some wound dusting powder (like cinnamon or sulfur powder) - the last isn't absolutely essential but it aids in the healing process after you perform the excision equivalent of 'Get thee out, Satan'.

No pic so this is a bit of a guess. From what you have said it is not rust (fungus), which can be red but always appears on the underside of the leaves. You say the weather has been very hot lately. Fuschias do not like heat so I wonder if this is a form of heat stress. Try shading the plants with something till it cools down a bit.

I grow a number of Circle of Life hybrids including; Pot. Martha Clarke (x Blc. Love Sound), Pot. Cayenne (x Blc. Buttercup), Pot. Lebenkreis (x Pot. Rubescence), Pot. Tokyo Life (provisional) (x Lc. Tokyo Magic), Golden Circle (x Blc. Goldenzelle), unnamed(x Slc. Final Touch), unnamed (x Lc. Irene Finney). I have been impressed with the overall quality of the flowers that I have seen(although not all of these have bloomed for me yet). I also have few plants of a remake of Circle of Life, plus some second generation crosses using Pot. Martha Clarke, and Pot. Golden Circle as parents, all of which came from Fred Clarke at Sunset Valley Orchids (SVO). None of these have bloomed for me yet (although they are close to blooming size), however I have seen photos of some already that show great promise. A friend of mine had a Pot. Tokyo Life (prov.) awarded an AM AOS this weekend at our local show in Toronto. It was from SVO. Peter T. Lin (who is in the process of naming the cross) and Fred Clarke apparently made the cross (using different cultivars) around the same time.

Arnold Schwarzenegger's anabolic steroids! No actually I repotted the mother plant earlier this year and this piece got accidentally dislodged. It really has 4 bpulbs and probably had already set the inflorescence. This is the routine appearance of this plant's flowers. Notice that it has brand new roots at the base of the closest bulb. Should make a new growth and bloom next year. Nick
