HELP!!!!!

riddleme · Nov 11, 2009

for others it would help to know more about the soil (medium) they are in

you should never feed a seedling!!!
20-20-20 has burned them would be my best guess and all I think you may be able to do is flush them and wait

but my best advice is to pm uncle ben send him a link to this thread and ask his opinion (he knows a lot!) be sure and tell him the medium your growing in, the lights your using and any and all nutes or additives

Good luck

i dont know what medium your using, but it looks like regular dirt... for seedlings you want a nice black soil that retains alot of moisture

The Medium is a nice soil organic with absolutely NO nutes; The mentioning of the 20-20-20 was just added yesterday AFTER they looked yellow because someone said they were lacking nitrogen.

ALSO I did specifed that I used 1/8-1/4 stregnth in a very weak solution of RO water

the top looks like it does because it has a layer of sand to keep out the soil bugs (the one thing i forgot was to bake my soil) so I put a toplayer of sand so the buggers cant get through.

ok thats what I thought but wasn't sure lol. what type of light are you using? yellowing is a sign of low nitrogen but it shouldn't be showing this early in the plant's life

Change the dirt. Get something like Promix or Happy frog for seedling . Dont overwater

6x 42 watt CFLs
2x 65 watt CFLs
4x 40 watt Daylight Flouros
1x 50 watt MH

2 x 3 x 3 box

8 inch fan blowing into the room with a passive exhaust, and a special active vent by the MH for heat dissipation.

Bump need real help started getting it then it dropped off

This is becomming a consistant problem. I germinate fine, I plant fine i sprout fine then they get to this point and just die. WTF 3 batches now will not grow past this point

This is supposed to be the easiest part. Your going to have a tough time with the rest of the grow cycle if you cant get past this. Use good soil, like fox farms ocean forest, keep it moist, plant the seed, and don't feed for 3-4 weeks (i went 6-7).

The soil your using looks horrible and dry like a dessert.
