Thanks for the reply. They look pretty mean, i suppose they are 2 weeks ahead of mine. I just did not drain the rockwool after soaking and the bottom slab has not lost a lot of moisture. I didnt pick up from the guides i read that i should drain rockwool and i only realised that rockwool will retain vast amounts of water after witnessing it and searching for it on forums (most guides say it is hard to over-water rockwool). I have just been trying to keep the top wet (i really have no idea how good at wicking rockwool is) and i have to give them some nutes!
