Hey everyone, First time DWC here. I was wondering if this looked normal for a DWC. This blue cheese from Barney's farm. Using GH series nutrients. Two air stones and top fed. 600w VIPARSPECTRA LED light. My concern is that the growth is slower than expected. It has now been three full weeks and seems like they are behind what I expected. Topped three of the plants about a week ago. Two of the five plants have wrinkled leafs, looks like the skin on fingers after being in water for a long time. Then most of the leafs look somewhat limp. They don't look to perky. Is this just part of the DWC until the roots grow more? The yellow arrow indicates a good example. Lastly, is it necessary to keep the top fed on once the roots reach the water? Thanks for any advice!
