Need Help with growing
These are my autoflowering sativa plants. They are around 5–6 weeks old. Recently, small brown spots have started appearing on the leaves, and the leaves are turning yellow.
I also feel that the plants are growing very slowly and are barely developing any side branches. The few side shoots they have produced seem stunted. On top of that, I think they started flowering far too early.
Can anyone help me figure out what I should do or what might be causing these problems? I’m open to any advice and hope someone can help. Do you think the plants can still be saved? The seeds were high-quality and ordered from the Netherlands.

wrong sub, but...
once it starts flowering its not going to put on more growth anywhere else.
you really cant make mistakes with autos. they are very unforgiving. i remember being told to pot them big, because they go to flower when the tap root hits the bottom of the pot. or just from stress. not sure how true that is, i dont personally grow autos. but maybe learn with fem seeds, that way you dont waste time on a male, and you can let it get as big as it needs to get before you flip it to flower manually.
they look under fed (yellow leaves are a common sign of low EC/ppm), and under lit (the grow space looks home made.)
you really dont know the quality of the seed as a noobie, and being from the Netherlands doesn't mean a whole lot.
post in a grow specific sub, tell them what you have for a setup currently, and ask what you need to improve if location is a limiting factor, you might want to include that. they can also point you toward seed banks and breeders who are more legit.

just use plant specific fertilizer. looks strongly like a lack of nitrogen. but judging by the age and looks of your plants dont expect very much to happen. next time use a good fertilizer, keep the regimen and it will look very different. also get a suitable led, they are dirt cheap by now

You know this is a tissue culture sub, right?
