Northern cali outdoor growing help first grower

ok so i have a plant that was handed down to me from my homeboy and its about one week old. thats what i think im not sure. The temp. gets to about 65 or 70 degrees here nothing above than that. I wasnt sure if i was supposed to give the plant 24/7 light so What i've been doing so far is leaving the plant outside from the time the sun comes up and goes down. then i bring it inside and leave it under a lil cheap light. I water alot too but thats only because the soil dry's up fast in the big pot. What ive also been doing is leaving it in my bathroom when i take a shower because it gets all foggy and i thougjt tht would simulate humidity for the plant. \
Questions i have are:
When should i add nuets?
Am i fucking up at all?
Its march here in northern cali so did i start late?
feel free to ask questions help please fellow Potsmokers
heres a pic of it

im in norcal too, we are at about 12 hours 6 min daylight your not late, stick your finger in the soil the surface myay just be dry? im not sure how big of pot but you may want to trans plant in reliable soil mix foxfarm ocean forest or something she will go through shock for a bit but it will be worth it beings the soil you have is drying out so fast.

good luck

i just noticed you had a picture, careful not to give too much sun, she needs to grow some roots if you feed nutes make sure its low in N. till she grows some.

peace

i havent got any nutes yet im going to buy floro grow and bloom. are those good? and the size of the pot is 5 gallon.
