I am growing dwc/aero. 18/6 light. 0ppm 1st week. 400ppm 2nd week. 1000ppm 3d week. 1250ppm right now. Pulled some clones last night, hope they make it... going to veg in 2 weeks, once the clones are rooted... once I have rooted clones I can yank males....... and flower all of them so that I know which clones to keep for the next generation...
