Little help...

[Holisticfarmer]

howdy
Seedlings are in their 3rd week. I've got them in black gold seedling mix.
Any thoughts as to what this browning/yellowing is caused from? My grow room exceeded 96 a few days which may have stressed them out a bit. I guess the browning is more of what I'm worried about. Any insight would be appreciated.

I was planning to start nutes after I transplanted into bigger pots.

do you let it dry out well before watering?

Yeah definitely. There was actually a day where I let it dry out a little more than I should have. The leaves were pretty wilted and I lost 1 seedling.

they have roots=they need nutes.

I agree. The plan is to introduce liquid nutes in the 3rd or 4th week

it looks like they are quite tall and stretched as well...i would ask what soil..im tempted to think there is something in the soil itself

 

[redeyedfrog]

Im in agreement with sunni, looks like hot soil to me. Dont feed em anything at all!

Temps during the day are around 80-85 lately. Night around 75-80. As I said earlier my room was reading between 97-99 for about a 3 day period. Soley because I live on the 3rd floor and it was humid as hell outside.

Sorry I should have clarified hot soil means soil too rich with nutrients, especially nitrogen.

my thought too. Soil is 70-80% blend sphagnum, peat moss, perlite, dolomite lime, yukka extract

what kinda lights are using?

how far away are they to the plants
if you put your hand to top of the plant does the light touch your hand? does your hand start to get really hot?

the more information the better the help you get

Stretch probably due to not having lights close enough initially

i would repot them and get them nice and snug like a bug in their soil just be very careful with the roots

im using a 250w hps (dimmable to 400w) Lights are about 6-7 inches away from tops of plants. Hand feels comfortably warm. Thanks for your feedback!

Thats a bad fucking ass feature on that 250w hps! They look a bit heat stressed and overwatered. But i see you've ruled out overwaterinf
