lst works well on most plants but you should wait until there are more sets of leaves developed as yours is way too young to be messed with mate

They are definitely too small and fragile for any lst at the size/stems they are currently. I would wait until they are a bit bigger and stronger in a couple weeks

Lst is great. Just they are too small to do anything yet. About 3 weeks in roughly is a good time to start and follow through till they finish.

Could have been something spilled on the leaves and some light burning from it, Could be the start or something else. Confirm your feeds are supplying all the recommended nutrients and if it is, this is likely just a one off, If it is progressing then its something you need to look deeper into. As your growing in soil and with RQS amendment pucks it will be harder to tell. If hey have not been amended they may need more soon. Normally its done every 3-4 weeks as a top dress with amendments. and if its getting runoff that will be leaching the soil a bit. hears a leaf chart that's pretty informative. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg Good Luck!

Hello, it could be a calcium deffiency but its hard to say for me because if it is then early stage. It also could be normal or some water that was on the leafs. Have other leafs the same problem too?

It could be nothing, like just a little water spilt on a leaf that's caused a little bleaching there. It could be the beginning of leaf septoria, which is also related to moisture on leaves but is fungal. Can usually see a little black spot in the center of the circle. www.growweedeasy.com/cannabis-plant-problems/yellow-leaf-spot-leaf-septoria
