[egz91]

Hi guys,
I planted a gorilla glie auto from fast buds 10 days ago and now leaves tipa and Borders are slightly turning light green. May Is not a big of a deal.
Tempo around 28 29 Celsius
Rh Is not the best 35 to 45 %
I am keeping a dome on top of the seedling to keep rh up a bit i spray It few times during the day water Only when the soil seems dry enough.
The light Is a 400w mh and i keep It 80cm away from the plant.
Helpe please i dont really know what to do.

I would keep that dome off my veg and flower is constant 45 rh and is fine. All that dome is doing is inviting mold

X2, lose the dome. It's a bad practice for seedlings, they need to transpire.

But rh is pretty low.

No it is soil with perlite Janeco lite mix atami

They grow in the Afghanistan desert. I suspect it's caused by too much light, a plant that small only needs 50 watts so raise the light all the way to the top.
