i have some seedlings that are 8 days old but by unforeseen circumstances they went from 18/6 for 6 days then had a 12/12 for 1 day then 18/6 for 1 day and now they had another 12/12. so in there 8 days they had 2 12/12 days what should i do now just leave them in 12/12 for the rest of there days or can i put them back to 18/6 tomorrow
