they are now 6 weeks old and about 2foot tall ,just put on 12/12 . everything looked ok to me up till last week , then leaves started to get brown spots on them then a few of them went yellow.
now the ones that had the spots have curled up as if they are dead but i can see the veins on the leaves are still alive , he has gave them one dose of epsom salt last week and then started to folar feed also fed them he is now lost with all the info about. i have looked it up for him and i think its a mg/zinc deff but i have never grown i just got it in a few plant abuse gides am i right or wrong ? i am not sure if anyone can help thanks

 

Check ph first off all. If that is OK give them a good flush. Then continue from there.

They are hungry, need humidity, and a balanced ph. A bit of dolimite in your soil may help.
