All of my tomatoes have leaves that are drying up and curling under.  any ideas as to what is going on?

Looks like too much heat/humidity issue. Mine only get that way when it is too humid and hot. It can't transpire.

Make sure it has a fan blowing on them.

I had the same problem with a few of mine, I had a fan on mine but I found the problem was I had them too close to each other so not enough air flow between them.  I spaced them out and kept the fan blowing and it seemed to help.

If they start to wilt like that, try giving them some vitamin B1 in water. Usually 1 or two tablespoons per gallon. It will help with the plant stress, leaves will perk up within hours. Valium for plants...

I really need to invest in a tower fan... My 80mm computer fans are not cutting it!

Have you tried liquid vitamin B1? Home Depot, Lowes, Ace Hardware, OSH, Tractor Supply all carry it.

I will look for it tomorrow. It is next to a nursery where I want to see if they will sell me 5-7 gallon pots for my peppers.  Craigslist wanted ad is also posted

@McGuiver I haven't tried the B1 yet, but maybe it is time. I'm really concerned about how my tomato plants are doing.  Any suggestions other than B1?
 
Big fan blowing on them for the past 5 days.
