Trouble growing indoors

[Autenthic]

Hello i'm having much trouble growing indoors.
Im growing in a 1.50-1.80m tent
400 hps light + a led 135w
i haven't got an extraction for air (notice that i air the tent as i open it next too my window every day)
im using coco soil + perlite soil + i add some extra coco .

I started of with 4 plants 2 died one from light the other was too weak im left with two plants that are looking pretty weak too me 17cm and mostly thin with 5 leafs up (i just toped it) the other i did not top is looking mor healthy and is starting too grow like it should (i think)

Is everting ok for the moment ? Also iam not an expert at growing .
ty for your answers

Hi, I'll ask the mods to move your question to FAQ, in the meantime it would be helpful if you could visit the grow support thread and fill out the form, here's the link.

Is your tent sealed, or do you have a way for fresh air to get in?

With autos you don't need to switch to 12/12. I just leave my on 18/6 for the full grow. If you system is closed, you might not have enough CO2 in the tent.

If I was you I'd buy a cheap temperature probe of some kind to keep an eye on your temps if you have no extraction. Also I've read quite a few people say not to top Auto flowers unless the getting all the right nutrients otherwise it can stunt there growth due to shock. If you want to do some training google low stress training on autos
