Little help please.

I didnt want to make a new thread just for my little problem but there are so many different things it could be I didnt want to diagnose this myself.

Just one leaf on my little girl is browning, I just want to make sure its not something that might spread.

Shes in flower from seed, no nutes yet, only about 2 weeks old, no sign of sex.

watered with tap water, under 108 watts of cfl. Leaf was not touching the lights or anything but I moved the lights a little just in case.

what do you think? PH? Heat? Nutes?



this is what it looked like 2 days ago.



thanks

no ideas? Just make an educated guess.

Two weeks old, no nutes and yellowing on a lower leaf? That's a sign the plant needs nitrogen. You didn't mention, but I'm guessing there are no nutrients in your soil.

Two weeks is generally the time you start fertilizing seedlings. If you're gonna use chemical fertilizer, start light at ¼ strength. If you're using quality organic ferts, follow the instructions on the bottle for seedlings.

yeah the soil was some scotts crap from home depot, nothing special. Any nutes in it have probably been used up by now. I'll add some of my nutes asap, thanks!

thats not yellowing thats browing. i bet its crisp.
its its crips its burn, id sugest flushing, i hope you use RO water...probably 1-2 liters ...

oh scotts brand it has chemical nutes premixed most likely...
thats the cause of the burn...
same problem as MG soils.

it will probably survive, there tender when that young, in a few weeks it wont get hurt anymore...maybe if hotspot..
