I have been away for ten days and left my friend to follow my instructions. Now that I am back things are not looking too good. They are big bud x northern light two month veg under 250hps 18/6 in a 2.5 gal dwc 10 ml nova bloom 12 ml cal mag 8ml silica ro water. Ph 5.8 up to 6.0. Anyway I have no idea what he has done can you guys help ? The top growth is looking fine but some of the bottom leaves are falling off and wilting and dying. I have done a flush since I have been back. Am I have nute probs ?
