My answer to everything: my tomatoes get foliage feed 50% MG. I mist when sun is hottest so respiration is high. If residue is problem rinse the whole plant down with your nutrients, 'full strength MG' claims it will not burn out door plants. I have not had a problem outdoors. Or on my seedlings following directions! If my girls are droopy they get folar sprayed until watering day.

I'm a bit confused about your setup. It sounds like your problem is a result of bombing for aphids, but the confusion lies in your HPA setup. You'r erunning 125 psi continiously? I don't even know how that's possible. What kind of pump & what kind of nozzles do you run? You know that in order to achieve the benefits of high pressure aero, you need to be cycling that mist to a degree not often even discussed on these forums. If you're running continious, you may as well be running a low pressure sump pump.

I hope you don't take this as an attack. It's just that HPA is the only subject I spend any time discussing on this forum.

Good luck.
