Ok today is the sixth week. All was going okay until I topped them then I started noticing brown spots on leaves progressively getting worse. growth has slowed now they definitely don't seem like 6 week old plants. Not sure if to start again with new seeds or carry on with these. I think the problem is root rot. Daily watering and my environment is cold and damp so coco does not dry out. Hopefully by next week they will be better if not will be poping more seeds
They not small at all pal. You can't judge a seedling by size for at least the 1st 14 days have passed then you'll know for sure if they are slow. To me, they look good.
Your RH is little low. I find that if I wet a bath towel and hang it from the top bar at the side of the tent. As it dries it'll bring her RH up 2 70+%.. but as I said. They look on track.
Enjoy the rest of your grow.
