Geeme you may be right I have used this season a Dutch organic soil medium called BioBizz ... the growth has been extraordinary on the majority of my plants which have shot up ... I feel I have underestimated the amount of nutrients mixed within the medium by adding more and this may well have produced these deformities ... strict diet of water for a whilegeeme said:I've only seen that kind of thing happen when a plant gets "topped" (either intentionally or through breakage) right above a growth node, in such a manner that most or all of the growth node is preserved. That aside, it looks like you may have been using too much fertilizer, so you may want to back off on that for a while.
