Holiday Avocado help, too much or too little water?

Holiday Avocado is struggling, any suggestions appreciated. Went in the ground on May 12th, thought sun was burning it up so I added the 30% shade screen after a couple of weeks but still no better and it dropped almost all of its avocados. Cant tell if it's root rot or under watering.
I recently put in mulch, previously there was none. I've also started using a 0-20gph micro sprinker to try to improved things by spreading out the water, previously was using a 0-14gph 360 dripper. Both were set to about half way for about 30 min 2-3 times per week.

What is that white stuff on the leaves and stem?

Some IV Organics sunscreen/oils paint like substance that I saw on youtube and bought on amazon. I tried to unsuccessfully dilute and spray it on as well but it clogged the spray bottle.

I don't think that is causing the drooping leaves but avocados like a lot of sun as they are a tropical plant. I would remove the shade cloth. IMO the cause of the drooping is a water issue. Too much water. They don't like wet feet and watering 2-3 times a week is excessive. A complete saturation every 10 days should be adequate. And it looks as if the soil is saturated now with all of that water draining out onto the concrete.

Thanks, i think I will reduce the watering. Wasn't sure what it was and wanted a second opinion before I added more or less water. The shade was recommended for areas above 100 deg, and its been in the high 90's recently. Just trying to prevent burn.
