This is my very first grow ("you're a hooker? and i thought i was doing so well!") with LowRyder feminized autos under MH light with drip nutes and RO water. Everything is on timers and i change the water and nutes every week. pH and PPM are within range. So, after 8 weeks i still have no flowers!!! Only misstep might be a Cal Mag dificiency early on, but since corrected. The plants look healthy and keep growing (now 36", no signs of males). Yesterday i switched to HPS light to mayb force flowering. What do you think?
