Help a a fellow grower ️

They look good and perfect time to do some grow techniq. Do You have other tent? Because if You want to fit 7 x 14l pots in that small area it will get crowdy. Whats Your light? I would move to final though. And about the nutes it depends on what You have already in the soil? Check Your runoff EC.

They look hella-happy. If the roots are coming out of the bottom, up-pot. You might want to only jump up a few pot sizes at a time to give the roots time to fill out the pot. Too big of a pot too soon and you could run into root/watering issues. When you transplant, they will probably go into a little shock. Try and give them a little more vegetation so they can better recover quickly.

I don’t think there is a right or wrong answer here. If it was me I would probably go straight into the final pot but not for about a week or when lots of roots are protruding from the bottom of the pot. Only thing with going to the larger pot is it tends to be easier to overwater them. Be careful on the volume of water you feed them and try and get a wet dry cycle of around 3-5 days. You would also be fine going into a 5L and letting them root into that pot and would probably be my advise to a new ish grower as if you did overwater the smaller pot would take less time to dry out. Also transplanting twice means transplant shock twice so it’s just really a decision for you to take👍 Last thing temp is fine but I am surprised your humidity is so low with a visible humidifier in the pictures. Don’t get me wrong your humidity is ok as I like about 60-65% which you are close to.
