Slowww

Esto ya me ha pasado anteriormente, no son los pequeños detalles como un un par de grados de temperatura ni un poquito más o menos de humedad. Se ve claramente que exageraste con las podas... La primera poda está demasiado baja, casi al segundo nudo, para la próxima permite que la planta se desarrolle un poco más para que no estanque el crecimiento al podar demasiado joven

If you are able to transfer each plant into their own pot (at least 3-5 gallon pot or a 30cm x 30cm growing container), a week later and you will find that they all perform nicely. They are looking good now, they just need space. RH 35% is too low, that's perfect during flowering period. For now, veg period, try to keep RH above 70%.

hey there Totony, the growth rate of the plant is determined by the metabolism and this is regulated by the relationship between the temperature and humidity. Right now you're at 35% humidity, you should be at around 75%. So one thing you can do is spray the plants with water or water 1mL/L calmag and water (twice a week) up to six times a day to maintain that level as close as possible. Another thing you can do is get a mister and just have that on in the room to keep the humidity up. A third thing you can do is get an evaporative cooler , that thing should stabilise the humidity at around 50-55% which is already going to be a lot better. Do this and you'll see a pretty huge difference in growth rates almost immediately. Hope this helps ! 🚀

A couple of things I'd like to mention here... first, your pot is pretty small so if these are photos, I'd transplant into at LEAST a 5 gallon if not a 10 or 15... The other thing is the distance you've got your lights from your grow... if you raise the lights up, the plants will stretch to try to reach it... I'd pull it up to at least 24" from the plants... Good looking grow otherwise! Good luck on getting the ladies to stretcchh...

Probably run out of root room from not filling your container right up. Rootbound in other words.

Most likely from environmental issues. Maybe to dry in the air. While vegging they like 50 to 60% on the RH

Log says you're running an HLG 260w LED. It shouldn't be causing that slow of growth. One thing I found was having slightly higher temperatures made a big difference. When running 24°c they were a bit slow for me. Once I bumped it to 26°c they took off. Also your humidity is a bit low for veg. If I was you I'd see if I could raise humidity and temp a little. Check a VPD chart for optimal ranges, I think I was around 26°c and 65%rh If that doesn't help I would start to think genetics may be a part of the issue. Either way looking good, hope you get it sorted, good luck.

Ehhh maybe. Which one is this the growers choice? Could just be shitty genetics. Inbred to the max suppressing vigor. Looks great tho, maybe it’s just not reactive to the training, etc.. some plants do not like to be trained
