Same nutrients as first week - 0.5ml/Litre of Advanced Micro, Grow, Bloom & CalMag. I religiously change water every 7 days. So far all water has been runoff from my portable A/C. Not much to see here...Luckily as my 'dinosaur' laptop did number twos & I lost a chunk of the hard drive which just happened to be my personal diary. I think the pics are back from day 17.
