Hi hwhobbs, glad to have you around, great advise too, thanks very much... Based on my last grow (1st grow) I don't think water temp is too high right now. Last time I was around 75f and everything went very well, no rot or scum at all. I only had it in the high 80's for a few days, no roots were around then, its been 75f the whole time basically and now its at 69 which I've never had. What is your temps? I thought 200ppm was a little low, at least based on my last grow, I had it at 600 or so by now. Do you think 400 would be a good number to aim for now or 500? I need to add some water tonight so I'll take it to 300. One thing I noticed in the last 48hrs or so is the ppm level hasn't dropped. When I had it at 150 and took it up to 200 in 24hrs it went down to 175 and 24hrs later it went down to 150, doesn't that mean that plants are taking the nutes? Thanks again for the help man!
