On week 4 they are still looking healthy one of the plants still has some leafs curling but it isn’t that big of an issue, also last week I had the coco wet for too long I think and ended up up having a little algae on top but I let it dry a little and used cinnamon and I think that did the trick.
Hi mate, She is looking healthy but i think she needs a feed. You can see this by the yellowing of leaves from the bottom up. She needs a little nitrogen. I hope this helps, good luck and happy growing
