Amnesia Lemon on Coco/Clay with Autopot

So the first week started and i just have to go for work for 4 days. At this point I thought it was enough to water them until they were really wet and that would be enough until I came back. They survived, but they didn't grow well. Unfortunately, I only realized my mistake on the 13th day and so didn't water them for a whole week. Well, mistakes are there to learn.
