Another week has passed.. By the end of week 1, I noticed some yellow veins in the new leaves. It looked like an iron deficiency. I was giving them filtered water, but it seems the filter took out lots of beneficial nutrients. As soon as I stopped filtering my water, the plants looked way better. I do got a bit of curled leaves, and I'm not fully sure if it's because of the filtered water I used or another issue. I slightly raised my lights just to be sure. Hope I can fix all issues this week and my plants didn't suffer too much.
