Does the Green Crack look like it is root bound, h...

A seedling in a 5 gal pot can’t be root bounded , high air temperatures isn’t really a problem if its get enough water , and I don’t see any nootz burns on your leaves.... it just takes time to grow cannabis bro

As far as its size, I think it looks very fine. Just different than the other one. Here's my simple 2 cents: Forget nutrients, heat or roots, the GC's leaf shape is definitely due to the wind from that fan on the right. It looks completely healthy and normal in all other regards. :)

5 gallon will not get rootbounf at 2 weeks, it's enough to grow, flower and harvest. What you can improve is your watering technique, you are over watering, by a lot, that's why the bottom soggy despiste the perlite. The water should last 4 or 5 days, the idea is to promote healthy root growth by making the plant hunt for water. At this stage give them 500 cc (17 oz), that should last them 5 days, when the soil is dry, repeat; when the watering lasts 2 days, double the watering amount, rinse and repeat.

Hello !! She seems to be really good at that stage , maybe a slight over feeding but really slight Root bound is impossible at that stage and with that pot size , it will be hard to bget root bound even at the end of your flowering. Ican see fans & a light that is not too close from the top of the plants so heat sould not be an issue ! I hope it will help you for the futur weeks

No worries it'll be fine!

Hi @therivernile ! She looks healthy, at this stage I won't worry too much. The curled leaves might just came from a slight under-watering combined with heat. You may remove those useless leaves in a couple of days anyway. You won't encounter rootbound in a 5gal container. About nutrients, it's hard to say since you don't provide informations about the meals you prepared neither than the EC of your waterings, but this does not look like a deficiency/toxicity. I see you're doing 24h schedule, be warned that both plants+lamps appreciate a few hours of 'pause'. Plants recover better at night, and stopping the light a few hours everyday will help in cooling down your environment. In this scenario, I'd try to reinforce the airflow, change the light schedule to 22/2, spray fresh RO water at night when the light is off, water more often and see how it goes.

Your plants look absolutely fine to me at this stage. I wouldn’t change anything at this stage. I think you’ll see nice healthy growth over the next few weeks if you keep on the same path. Also I dig your tent layout and lighting! Well done! 👍
