-- A bit of brown slimey crap appeared on the roots. Added some cannazym (which I had neglected to previously) and after a few days the roots were nice and bright white again.
-- Again, just astounded at the growth rate with DWC. Couldn't keep up with nutes and so another bloody mag deficiency appearing. Got onto it with additional nutes, I did lapse in testing ppm and they had just drunk up all the nutes.
