good day, i have a huge bottle gourd plant side by side with Ridged Gourd gigantic plants.the bottle gourd is 4 month old but it does not producing full size fruit. despite my carful hand pollination the fruit could not be set. infact the little gourd get some spots wich are indeed scratch marks and the juice comes out of this , dries up and leave these mark. i wonder if this is a disease or some other indication. on my end watering, fertiilizing( only old manur) and soil combination is seemed to be ok but the result is discouraging. by the way ridged gourd producing apprpriate fruit. see the images regards
