I started a new grow and I was curious how long you should go without giving nutrients. Started them off in solo cups, then to one gallon pots and now I just transplanted to five gallon pots. I'm on day 34 and I'm using FFOF soil which is full of good stuff. Given only water thus far with Calmag and my last run off was around 1700 ppm's on average and 6.5 PH. Any thoughts? They are all looking very healthy.
