>Would like to know how long it takes to notice problem ? >and what are the early signs ? I have gotten pretty good at telling when blossoms are going to set fruit or drop. It doesn't seem to matter what is causing the drop ( temps too high/low, excess N, not pollinated... ). The thing I watch is the stem running from the branch node to the back of the flower (the pedicel, I think it's called?). If this starts to thicken up at about the time when the flower is dying back, then the fruit will probably set. If the petals drop and the stem hasn't beefed up it's appearance, it will probably fade from green to pale-green/yellow and drop. My Bulgarian Carrots in the pot are setting fruit. The Kalosca Paprika and aji limon are blooming, but dropping. All other annuum are just starting to form buds. All chinense showing vigorous growth but are still relatively short and no sign of buds.
