Hi

Im trying to grow tomatoes on my balcony, its not very large so I've picked cherry tomatoes that don't grow tall for pots. 4 in very large deep pots, and 4 in small pots that I can move around. (2 in each pot).

I noticed that a pair in one of the smaller pots started to show signs of something eating the leaves (white specs) I couldn't see any bugs, other then the occasional gnat or two flying around, none of the others had anything on their leaves so I brought just the one pot inside to keep an eye on them and so whatever was eating it wouldn't spread. I kept it by the window, it gets around 4-5 hours direct morning sun so I thought this would be enough.

It seemed to be doing great, no more signs of damage for a few days, then almost over night, both plants had curled stems, only one stem and the same stem on each plant, the next day, another stem started to curl downward.

Well I hadn't have watered them in some time and I thought they were just thirsty, it had just started to pour down raining outside, so I throw the pot back outside with the others.

I checked the following morning and more curling! and now the leaves seem to have begun to shrivel up, a few leaves have already shrivelled up at the stem and fallen off, because of the rain they are not dry, but id imagine they would be if it weren't for the rain. I've brought it back inside to keep it separate from the others as no other plaints are effected and they all seem to be doing great, I don't want whatever has caused this to spread. Ive got the effected pot by the window again.

Hope I linked these images right

Is this something serious or will the plant recover and begin looking like all the others again?

Looking for any advise on what can I be done or if I should just give up on these two.

Thanks
