Hi. My first grow and my first post (problems straight away):
Setup: Secret Jardin DS 90
400w HPS - (250w CFL blue spectrum is on its way - fucking snow in UK everywhere so the post its late)
4" extractor with carbon filter
Temp - between 21 and 27 C (Max 30, min 18 at night)
Humidity - RH low 30%
Soil: B.A.C. Lava-Soil

No nutes.


Started the seeds under 400w HPS 3 feet up.
Don't know why but I have put my seedlings in the fiber cups - think it was a bad idea...anyway
Seedlings (white dwarf auto) are in heated propagator - heating on over night as the temp in the room with the tent goes down to 18C

They all sprouted (five of them) - the strongest one is nearly touching the propagator cover (cover is over the plants to keep the humidity up).

Today (06/12 - one week into grow) I have removed the strongest and biggest seedling out of the humidity dome and after 8 hours one leaf looks like it partial dried out .Pls see the photo. Does it dried due to light intensity and low hum? Or is it something else. Also one other seedling have a yellow tip on the end of the leaf.

Please advise. Yo.
