My exhaust fan is very strong. I had very huge issues with heat before. My last auto grow was ruined by heat. It was near end at mid July and tent was over 40C with wing reflector. So i bought cooltube and small exhaust fan but it wasn't enough strong to cool. So i went for biggest exhaust fan to make it cool and decreased to 30C mid summer.

I even stop exhaust fan and open window for fresh air now when lights off. If it's on when lights off, fan lowering temp in tent to 16C.

This is biggest issue with HID bulbs. Heat.

AC is big solution but growing weed illegal here and high bills are suspicious where i am living at.

the bigest problem is heat, with all the money your throwing at a few seedlings, just invest in a cooltube light reflector, that will cut your direct heat problem down somewhat and getting an extraction fan and flexi hose to put it in one of the holes in the top or sides of the tent, if its anything like my tent, there are holes for fans cooling tubes all over the place, so you can put any kind of cooling system into it, it was well worth spending the money on a great tent, instead of an allright tent.
shit, for the money your spending on that 1000w light, you can afford a small 250w mh, there cheap as chips these days, as everythings LED for climates and growing enviroments like yours
i would have sugested, well i do for next time, useing 9" pots to germ the seeds in, a 100w led unit. you could go 2 units and have 5 plants under them no problem.
you have those seedlings in way bigger pots then they need or even like, from what ive learnt over the years, germ in 9" pots untill they outgrow them, then go to 11 gallon then 5 ect. you will get more compact plants and get a higher return if you just do these simple things.
a couple of led's would be a very wise investment given the cost of electricity these days and you wont need anything else bar a fan to give the plants stronger stems and shorter stems

Do You think they have eaten all the dirt and need extra nutes?

Medium is peat soil so no nutes in it. Also using Biocanna products. Maybe i would go for Rhizotonic only for root support. Yeah its not good idea to start nutes too early. Most of sources recommend to start nutes after week 2 or 3.

Not sure about starting nutes yet. Do you think i should not?

This is my first time photoperiod grow. I went for autos. So autos always starts and ends in final pot as you know.

Next time i will start with cups or small pots and with 250w MH. Then transplant to big pots. I know i am wasting my bulb now but i already started and in day 11 now. So anohter week or so real veg starts.

as amnesia stated, your useing large pots, so watering flushes the nutrients out of the soil from top to bottom, washing it out of the soil, asll the more reason for useing smaller pots.
you could do worse then inverting a small plastic drinks bottle with a drip top for plants, it wouldent cast too much shadow , plus seedlings get away without direct light in nature, they grow up to the canopy and then get direct sunlight.
that way your not flooding as you water, youre getting directed water to the seedling.
if you have indeed washed all or most of the nutriens from the soil, try a folier feed with a spray bottle, do this during lights out, so you dont scortch the seedlings delcate leaves.
just feeding a week seaweed solution will be enough for the seedlings. allways wash the leaves with clean water after folier feeding, not strait away obviously, or your washing the nutrients away that you've just applied, but give it a good few hours b4 fresh water spray, and make sure the plants are dry b4 lights back on, ie, no visable droplets of water, any excess moisture shou;ld dry as the lights warm up the grow room. but droplets act like a magnifing glass lense and will burn them bad

Update time.

Day 13 since breaking soil.

Almost 2 weeks is over. It took so long to soil gets dry. It wasn't so good idea to saturate whole pot at first watering. Anyway, there is not much bad signs. Twisted leaves keeps going on new growth. Raised light about 100cm away.

Day 13 1.jpg
Day 13 2.jpg
Day 13 3.jpg

Now they are in dark period. When lights on (7 hours later) i will water them because pots are easy to lift. 3rd set of leaves are very obvious now. Signs of 4th set of leaves at first plant. Today i will start with light feeding schedule on companys chart. It says 2mL vega and 2 mL rhizotonic for 1 liter of water. My soil is regular peat soil from hardware store. So no nutes in in at all. And i want to see how nutes works with this brand because i am used to go with AN. So let's see what happens.

You should really get a MH bulb for veg.
You may also wanna think about your yield expectations again.

Why?

I know they look like a bit behind of schedule for 2 week but i can veg them extra 2 weeks no problem. My last run with autos under very high heat conditions was 0.4 gpw. Yeah maybe 1 gpw is hard but 0.6 or 0.7 is doable.

1g/w quality weed with hps takes skills. Even for 0.6-0.7 you need to know what you are doing, its not bad either.

Anyway good luck with your grow, i hope u get what u reach!

hps has lots of iR making the plant strech a little more. while mh makes your plants shorts and bushy. you would get better results in the end

Critical is probably a strain that can give it to you. 100 cm is about where I’m at on 600watt (3ft). I like a bit of stretch with HPS when using scrog, makes things easier (I have 1 MH bulb and a Far Red LED in room too) Never like advanced nutes, fuckin 1000 adds, I’d go Athena or Jacks but I’m Jacks. I’m running 5200 Watts with CO2 and haven’t hit 1 GPW in a while (I choose keepers for quality not quantity these days). I remember watching Sato I think hit 2 GPW. Another member did when they built their own COB light strip back in the day so it’s possible. Good luck.

Yeah 1 gpw especially for beginners like me is probably impossible but that's my motivation :) I am okay with 0.6 or highest 0.7 gpw. I am going to veg them 7 weeks in 20 liters pot with Biocanna line. So 3,5 weeks veg and 7 weeks flowering with my autos and 0.4 gpw even with heat stress and last two weeks issues with overfeeding. So with good care 0.6 wouldn't be so hard imo. But i don't know. We will see day by day.
