This is a case in point for organic gardeners. I'm not saying that we don't
use some safer soap for problems, but you may be over zealous when it comes
to bugs and applying soap or other products. First off, are your plants
being severely chewed by hornworms or by aphids sucking the juices from the
leaves? Those two bugs would prompt use of soap if they were heavily
infesting the plants. If you see hornworms, hand pick them and drop them in
a bowl of dish liquid and water to kill them. I use gloves, ick!

If you have other bugs, they may be beneficial bugs that will eat the bad
bugs. My point is, if you see no damage being done to the plants, don't
mess with the bugs. They may be your friends. Plants always have bugs on
them for good reason, that also includes spiders who catch many bugs for us.

I would lay off the spraying for awhile and just water your plants. Yes,
too much nitrogen/fertilizer will produce lush, green plants with no fruit
too. My tomatoes produce hundreds of pounds of tomatoes each year. I never
use sprays on them because it may burn the leaves or wreak havoc with the
flower producing. When I plant my tomatoes, I throw a banana (yes, banana's
have potassium) in the hole with a handful of epsom salts (magnesium) and
cover with composted manure. I plant the tomatoes on top of this without
letting the roots touch them. I also plant the tomatoes at least halfway up
the stalk to produce a deep root to protect from wind and rain damage. I
work in Garden Tone Fertilizer around the top of the plants in the first few
inches of soil. I then top dress again with homemade compost to mulch them.
I water twice a week deeply. I also spray or water in the plants with fish
emulsion once a month to boost them in the stress of summer. Once the
tomatoes start to ripen, I cut back on the watering so they produce sweeter
tomatoes. Too much watering at this time, will produce watery tasting
tomatoes.

I hope this helps and your plants recover so you can enjoy your tomatoes
this season.

Every two weeks I started sparying diluted dish washing soap and found
that plants are growing up very healthy but flowers /buds started
falling off. I found out after 2 months the reason is soap spray, I
never had one tomato even though they are very healthy . Initially I
thought it is because of too much nitrogen, and started feeding them
tomato bloom fertilizer. Still no fruits. Because of so many bugs
where I live in florida, I had to use the spray. Next time I will be
careful, but I don't have any other way to keep crawlers/bugs out. Any
suggestions?

Thanks
