Could yellowing of leaves on seedlings be from too much fertilizer ( liquid fish, compost,seaweed type.)
I wouldn't suspect iron deficiency as it is new premium potting mix that they are planted in.
I did feed with about half strength liquid feet about 5 days ago.
Yes I would say it's a little bit of iron defiency . I add calmag plus which contains iron as I used to have this problem but it's stopped now .
Also what leaf blower said was true . You may already have iron in your soil but if it's not at the correct PH the plant won't absorb it. So checking PH is the first thing you should do . If that's fine maybe add a little more calmag plus if it contains iron .
Thanks, a very unconventional grow, but I think it will be ok in the end but not much quantity I think due to the fact that it has been grown in mid winter.
