new plant showingyellow on leaf

[divaling]

Hi,
I had 2 seeds left from last year so decided to plant them up, its only my second time of growing, so a newbie.
Both plants started growing quite quick, one looks strong and healthy, the other has yellow marks on the lower leaf,
and the next leaf up has a bit of yellow at edge. They are 2 diferent variety, do you think the yellowing is okay, I'm growing in a pollytunnel, dont know if that makes a difference. As I'm in lockdown in the UK I don't have access to more seeds, so was hoping these would grow, any thoughts please.

What kind of soil is it ? What is the PH level?
do you have drainage in the polytunnel/pot?
what about nutrients?

Wow Captain! Great minds think alike!

[F10werChyld]

What are you growing them in? Do you have a way to check the pH? Are you using any nutrients yet or just water?

Wouldn’t say I’m a great mind. Spent 5 years in the army as a professional.. to many years to long. What is why I’m sick now and growing for my PTSD. But thank you for the compliment! I always appreciate kind words👍🏻

standard approching nute burn

IMO: potup to the next size pot add 30% perlite or clean river sand
mix well..and potup.. no nutes for 2 weeks
consider applying neem oil to prevent any PM and bugs later

good luck

Thanks for your replies, I'm not very up on PH LEVELS. there potted up in ordinary potting compost, in pots with drainage. I have re-potted both but obviously the yellowed leaf wont change, just hoping new leaves look better, the other stronger one is doing great with same conditions, but they were different seeds. will have to look up neem oil, I havn't heard of it. Will re-post in a month or two to show how there getting on.
