What is good for aphids and getting under the leaves?

I thought aphids just got on stems but the f***kers hide under leaves. I have a gallon sprayer and can get under there. Bombing with Doctor Doom in the morning then going to MMJ supply store - they carry every thing.

Mighty Wash or AzaMax? Green Wash? 100% Neem? Pyrethium bomb? Knock Out?

I have Neem but it is not the 100% Dyna Gro. I have Neem Py (ferti Lome) which they sold me last time. Also I have Organicide 3 and 1 with fish oil. I am trying canola oil, water and a few drops of Dawn tonight.

I am also thinking of spending $150 for a fogger. My 1 gallon sprays mists but fogging may be better.

Thanks for any help.

Determine what they are first. Sounds like mites. I don't think aphids reside on leaves. Usually in the root system or soil. Get that sprayer and a mixture of pesticides. I like Azamax, green clean and sns. Rotate them weekly so the bugs don't get immune to them. Make sure you spray well. I make a gallon of whatever I'm using and spray it ALL. Get full coverage.

They appear to be aphids. They are on the stems and I realized aphids are also under leaves like mites. I am relatively new. They are big enough to be seen and spider mites are harder to see. Thanks for tips.
