I have had an early fair plant growing for quite some time now. It was doing great until last weeks cold snap. We had frost two nights in a row and daytime temps in the upper 50's. A few days later I started to notice some yellowing in the older leaves near the main vine.

I saw a recent post by another grower of something similar. Did this recent cold snap cause this ?

Will the plant green up with the summer like temps I now have ?
All of the new growth seems to be normal except for two small leaves in the first picture below.Also, the plant has really picked up in growth the past two days with the warmth.
I will post a few links of the leaves and my spring soil report.

I'm noticing it on all plants that were not in hoop house, but all big plants from hoops are fine. Soil dipped into the upper 50's during cold spell.

ZAPPA I've got some leaves on my early plant that look exactly the same as yours (despite hoop house, space heater, soil heating cables, etc.) Seems like every year there are some funky looking leaves when the plant is young/early in the season. They've always snapped out of it as soon as the hoop house is off, and the weather warms up. Although it doesn't stop me from worrying!

I have never dealt with frost on my plants, but I'd assume a couple of those leaves look like they were bitten or close to it. Good luck!

Nitrogen got goofed up - probably because of the cold.

Thanks folks, I will see if this warm weather changes the color back to green.

I would say 100% just too cold we have had it lots of times absolutely nothing to worry about and as soon as it warms up the plants will fine.

Lee look up pics of salt damage. Got one here that I know I double dipped on N and then the sun came out. Looks just like yours.
