I use to use it when i serviced commercial aeroponic systems. its really for insects and not so much for foliar feeding. i would dilute it and add a few drops of dishwashing soap. It can also be used systemically (directly in the reservoir)

if youre trying to prevent or kill bugs it is about as god as using dish soap with vegetable oil. nothing special

is you want it for foliar feeding, id prefer a good calmag or even GH Florolicious Plus
