Sweet seeds has said enough bro. The problem started with your medium.
You’re soil does not contain enough oxygen due to a mix of 3 things poor drainage, low evaporation rate, lack of root growth. Big roots, Big shoots!!
It is right that you shouldn’t transplant autos.
It can be successfully done but you are playing with fire by doing it.
The pot you are using should be fine it’s all about how you water (Volume and time between watering) that’s most important.
1.) use a good soil. Use perlite or vermiculite as you have. 60/40 soil to perlite is enough.
2.) seedlings need just a very small amount of water you do not need to drench the entire pot every time you water. 500ml - 1L every 3-4 should be enough for a plant grown from seed.
I like to pre water the soil to moisten it leave it for a day or 2 under my lights before I plant the seedling then I spray using a mister and some tap water, add some root booster if you have them I use rhizotonic and voodoo juice. I Spray the top of the soil every other day for a week, with no more than 250ml.
3.) when your plant is in its vegitive stage usually after about 3 weeks the you can start drenching the pot. The finger in the pot method is not a good method IMO picking the pot up and observing the leaves is the best. When you water you will notice the leaves sag... after a day they should pick back up... then as the soil is drying up and the leaves start to “pray” towards the light. Pick the pot up at this point if it still feels a little heavy wait 12hrs - 1 day.
I hope this information will help you with your next grow. I’m afraid you can expect much to happen now it’s too late. Yes you may get some developed flowers. Take it as experience and learn from it.
I can see Sweet seeds has tried to help during the process but I guess you didn’t hear what they where trying to tell you about watering and feeding. I have broken down the basic way to keep your plant alive.
Look at it this way, you plant the seed and leave the plant in a tent with some fans and a light on a timer. (Of course a light suitable for growing)
Our only job as a grower is to water it to keep it alive. So that is the most important aspect of growing to get right. Watering includes: nutrients, ppm, ph, water temp, oxygen, volume and timing. Research these things in fine detail, and try to better understand the help you have been given. I understand this might not be the way others do it, but from the information I have gathered from your diary my suggestion would fit your problem. All the best✌️🏻
