i have a few problems with my tomato plants idk if it's due to weather or what.

the weather has been raining off and on lately.

here are the problems i would like some solutions that won't kill the plant and is organic for the most part.

1. white flies- theirs a bunch of them under the leaves scattered around the plant. how do i get rid of them? also what are they and what causes them? they are very tiny but you can tell they are flies not aphids and they are white.

2. mold growing under some leaves- whats causing it? the excess rain? it's white and only under a few leaves. how do i get rid of it? should i just trim the leaves that do have it?

3. some leaves near the very bottom are turning splotchy. it's the leaves you normally trim off due to disease/mold and i did trim them off as they started growing mold but they grew back. do i keep trimming it off? and why is it turning that way. im sure it's some sort of diseases. it's only happening on the bottom leaves for the most part. the leaves are green but their are dots and it's turning a yellow color. the dots are yellowish. how can i prevent this and how do i deal with it? this never happened to me the most i had to deal with are mold and aphids. the aphids are gone. the mold has come with the weather i believe.

any help? this is my last tomato plant i really don't want it to succumb to disease/pests it just started to flower ):

For both the whiteflies and the mold (actually called white powdery mildew), you can use a spray nozzle that generates a strong, fine spray to remove them (strong enough to clean the leaves, but not so strong that it damages them). A teaspoon or so of dishwashing liquid in a quart spray bottle is also a good organic bug spray. And, splotchy leaves on the bottom is normal for a tomato plant, as long as the new leaves on top are healthy.

First off, sorry to hear about your dad. My condolences to you and your household. It is particularly no longer that complicated to grow tomatoes. Given that they're by and large already establish, you must simply keep them tied up (if utilising stakes) as they grow and furnish about 1 inch of water per week. If you are having very scorching dry weather then watering them some each morning may aid, simply attempt to hinder over watering them. Once they to bloom and form fruit, which you could provide them a bit of tomato fertilizer. Tomato-tone is my favorite natural tomato fertilizer. This is quite optional as they do not particularly need as much fertilizer as most individuals believe if you have just right soil.

for the powdery mildew, mix whole milk and water 50/50 and spray the plants. also, if you have epsom salts (the kind you soak in) add about 3 tablespoons to the base of the plant and give them a little water. epsom salts is magnesium sulphate, tomatoes love both magnesium and sulfur. for the bugs, try dish soap and water.
