Also some are yellow at bottom not too many just worried it may get worse... Other than that they seem green and healthy

The top pic is environmental damage - sun scorch. Were they well hardened off prior to transplanting outdoors? Those leaves may die and fall off but pose no threat to the plant as long as the new growth looks ok.

The second pic looks like some possible just-beginning disease issue from the contact with the soil. Would need to see a close up of the leaf to know for sure as it could also just be some sun scorch.

Any branches that have direct contact with the soil need to be removed when planting.

Be sure to mulch all the plants well as soon as your soil temps warm enough.

.....plus, in general the plants look ok. I might give them a bit more food.

I tend to take the bottom leaves off on most plants just because they are ususaly damaged from soil contact or bug exposure etc. I don't think it matters too much

I think this common practice of removing leaves is a bit misleading. You are removing source of obtaining nutrients from the plant and stressing plant in addition making it more susceptible to other problems. Even if plant has fungal problem on the leaf do you remove the problem when you remove the leaf...
Plant is doing ok, leaves are ok, environmental damage, leave it be, new suckers are coming. Put some straw under lower leaves.
