I have 4 plants that are grown in 30% coco, 30% perlite, 30% compost, 10% wormcastings and some amendment like bone meal, rock dust, atlantic mix of kelp and other amendments.
They started out with small dots and i thought it was some small heat stress as we have had some hot days. But i then discovered white flies and winged fungus gnats. I went out and got a organic pesticide and sprayed it on. The white flies were gone and the plants looked healthy but today they are looking much worse. I don't know if it is a bacteria, a insect or under/over nutrient.
I did give some vermi tea at the end of last week.
I give my plants rain water that i save in a big 500 litre tank. I ensure my pH is 6 to 6.5 range. They are small and in an average of 15 litre pots. I am watering about 250ml of water each morning as the heat is drying them out fast and i do not want to run risk of overwatering.
Any help or advice will be much apreciated.
Note: 4 different strains from white widow to durban poison.
