Just curious

I’m in my fifth week and one of my plants is growing great but the other four are the size of the smaller one. Does anyone think I’m doing something wrong? Or do some plants just grow at a different rate

They seem a little overwatered, the back has some claws so could be a bit too much nitrogen, the leaves are showing heat stress or overwatering as i mentioned.

But as for some plants bwing smaller there is a massive difference in pheno types and one plant may be huge with the other small especially with hybrids which most strains are now.

What are your temps ?, watering schedule ?, medium ?, and can you get a pic without the leds on so we can see the leaves ?
