I have been hardening off brussel sprout and broccoli seedlings for about a week and a half now and some of the leaves have been showing light spots and even some small holes. Last week it was pretty sunny out so I think this may be sun scald but I'm not sure. Can anyone confirm my suspicions? If it is sun scald should I clip off the damaged leaves?

Also, currently they are planted in individual coir pots. I would like to plant them in their permanent containers this weekend. I am going to attempt the 5-1-1 mix but can anyone tell me if I can just plant the whole pot in the new soil or if it would be better to remove it?

Thank you!
