Rhubarb start leaves turning yellow - help? (flower, tomato, planting)

[Opyelie]

It's still raining here every day, so haven't made the move to put my plants outside yet.

Suddenly I find my rhubarb starts have their leaves turning soft and yellow. Is this too much water, too little?

Should I transplant them into larger pots from their starter "pots" ?

I got 4 plants thinking if I killed off 3 somehow, I'd at least get one adult plant from it.

My herbs that I started as seed in those little windowsill "greenhouses" are getting too big for those pots/covers as well, so I've taken their "lids" off and will see what happens.

So far my two tomato starts are going well, I put them outside to enjoy the sun (when there is any) but now they are both starting to flower and I'm thinking I'll have to repot those before the weather turns nice enough to put them outside as well.

I would think that the rhubarb would do better in the ground.

yellow usually means too much water. I''d put them in the ground too.

Unfortunately I'm renting so planting them in the ground isn't an option. Once I get a thriving plant I'll transplant it into a VERY large container (one of those half wine barrel things), but for now maybe into say 1 gallon pots and see how they do?

Maybe the starter pots they came in didn't have enough drainage - will transplant them into larger pots and see how they do. I'd LOVE to be able to put them outside if this rain ever stops - maybe under the eaves where they don't get hammered by rain?
