thanks for any help i really wanna fix my seedling but something tells me it may be too late thanks

dont spray or feed any nutrients for the 1st 2-3 weeks the plant is too small and cant handle it, most mediums come with a little fert in them so this will do ur plant thru the 1st cpl weeks, try just watering for the nxt week and they should hopefully perk up, the damaged leaves wont get better but new growth shud be nice and green

hey bud on 2 of them roots popping out the bottom does this mean i should put them in new pots or should i resolve this issue 1st thanks m8

yeah get them in bigger pots and only use water like i said for the nxt week.

thanks bud so much i get pots and sort

Wow man, you got alot goin on over there. Coco, rockwool cubes, dirt with pearlite, dirt with sand....and the post kinda reads like stereo instructions.
I think watering the tray is probably whats killing it. Your probably drowning it because it has to suck water up rather than...well whatever, just water from the top and make sure your letting them dry out between waterings or they droop.
The other thing it may be is the bugs. You say somthing about stopping pests. Do you have fungus gnats? Mites? Cause mites yellow up the leaves pretty fast. Id guess one of those two things. Good luck.

How long have you grown in regular soil?

1st time bud in soil and have hydro aswell which is running sweet but i used clones from a friend then. this time i bought seeds and wanted to get a good mother to keep

Quit foliar feeding unless you know what you are doing....

my seedlings don't help me much either...lol. get it. your 12 day old seedling is bad help.

Take my words bro
TRANSPLANT asap to a bigger pot and stop feeding and you will see a quick improvement, be careful when you transplant to prevent shock
