Unknown deficiency maybe? Help, no nutes added.

I've got a 4week 3days old Gelato strain from a bud I bought (aka bag seeds). I am starting to notice some of the edges of leaves are curled up in newer growth (some pictures below). I first thought it was temperature but my room closet never goes above 75°f. Also some weird new growth from one of the side shoots. I just need some advice befor I go puting nutrients and f things up.
Room & Plant Info.
Bedroom, in closet also has a/c unit.
1x35w t8 led strip. (18/6)hrs
2x12v cpu fan for fresh air in closet. (Ik lol)
Peat soil medium with perlite.
No nutrients has ever bin added.
Bought general hydroponics flora series today.
Water every 5days (peat soil holds plenty water).
2 more days for next watering.
No pH tester :(.

Hi Dan,
You didn't mention humidity...rh is important. Too dry and they have problems...to humid, you risk mold. My point is it's something you should measure and be prepared to correct. Plants don't look that bad to me.

Just read your profile post...so you're in the tropics. Humidity shouldn't me an issue. Worked with a guy from Trinidad...liked to cook eat and listen to kettle drums. Big party dude.

So you can't grow outside there yet? Not the right time of year anyway. Later...

yes we live to party, carnival time over here is the bomb!!

Over here in trinidad the light cycle varies from 11/13 to 12/12 for the two seasons we have which is "Dry Season" & "Rainy Season" so outdoor plants has to vegi indoors anyways, that's why I just decided to keep it indoors.

Forgot for a second how far south you are. Be good for growing sativas. But growing indoors is fun too...and fewer bugs usually. lol
