Hey guys I've been browsing the forums and finally decided to join the community and maybe get some help in the process. So here's my situation.. Seeing as how I can grow legally now I decided to give dwc a try. I currently have... 8 nipple air pump 4x 5Gal buckets with 6" net pots (2 w/ 1 air stone and 2 w/ 2 air stones per bucket) 400w ballast and an air cooled hood running a MH currently Now onto the ladies.. I have one cream caramel regular plant, two afghan kush rider auto flowering, one la chocolat auto flowering, and one Pineapple Express auto flowering. I'm using advanced nutrients 3 part GMB and B-52 at half dose in tap water. I never planned on using tap but numerous people claim with the water in our area they never have to do the letting it sit for 24hr. I always check the PH level and always at 5.5 for all of them. I checked my plants and they all had yellow spots on their leaves. Freaking out I check to make sure there aren't any mites or bugs and couldn't see any. The cream caramel (regular plant) grew out of it in a day or two and is doing great but the auto flowering ones look like their getting worse! I took some pics to show you what I mean. Any help would be greatly appreciated! Thanks!
