Until you supply particulars, the answers must necessarily be vague in order that they are not totally off the mark. You should learn what cultural conditions the plant prefers and do your best to provide them. Among them, I'm sure, is to keep actual soil temperatures below 90* (you may need to shade the container) and don't over/under-water. Be very careful about applying fertilizers when temperatures are high, as well. Al

These plants have a milky white sap, as do many other members of this plant family. What you've been observing is perfectly normal.

Hmm. I thought I'd wait until someone who grows their own seedlings would respond. My opinion is that it's a cultural and/or physiological situation. The reason: almost all the spots are near the edge of the leaves. Further, doesn't look like any disease. Don't know what the weather conditions are in your region. But if possible, I'd get them into the garden, with protection if needed.

The plants in self-watering containers and in 5-gallon grow bags are both exhibiting the leaf roll. However, I do have 2 5-gallon grow bags that have plants in partial shade which do not exhibit leaf roll and are just as big, if not bigger, than those in the self-watering containers. I'm thinking the leaf roll may be root stress related. Either the 5-gallon containers/bags have become too small, the container gets too hot thus stressing the roots, or the potting soil has finally compacted and isn't delivering enough oxygen to the roots. I have tomato plants in raised beds as well and I haven't noticed any leaf roll with them. I have noticed a few had yellowing leaves w/brown spots (3rd picture), however.
