Clones curling up

I have three clones in Solo cups and 1 seedling in a solo cup. The seedling is healthy but all of a sudden the clones look unhealthy. I need to repot these but I'm waiting on some soil amendments that have been delayed because of 2020 craziness.

I plan to put these in 15 gallon pots, should I just go ahead and up pot to a 1-gallon until the rest of my amendments come?

I hadn't checked on them in a day or so, I suppose they could have got thirsty but when I water them they didn't seem like they were that dried out.

This is no good, these clones are from my final Run this year

Looks like sun or wind burn.

Well it was really hot, and then it got really windy, and these are outside.

But they dont get sun all day, and they had been outside for a while in the same spot they are in.

I think I better go ahead and repot

I typically like to baby my clones until they are fairly strong. I don't typically expose clones to full sun light. You want them to focus on building a root system not throwing out leaves. How well rooted are they?

They were rooted in water bottles, then transferred to Solo cups.

They were under a veg light for about 4 weeks then transferred to the spot they are outside at now. But the spot that are in now only get sporadic sunlight for a few hours a day. Then it's in the shade. I've done young plants in this spot before not had a problem.

It's likely from that hot day that snuck up on me the other day. It was really windy and it was really hot. By the time I got home from work it was back to cool cloudy and raining. It was a weird midwest weather day
