Hello, Please someone tell me what to do. I'm beginner in indoor growing and my plants are a month old. I used NPK fertilizer (one teaspoon in a liter of water) and watered my four plants. three of them have started bending down their leaves as well as bending of the stem close to leaves. I...

What's up Rollitup, hope everybody is doing well and taking it easy :) It's that time of year again, except this year tackling the nearest person to your left in a desperate bid to grab that last 98" TV or 18 part Toaster is ironically too dangerous, no matter how great the deal. :roll: In...

i hung a bud in a shoe box in my closet to dry and in about 2-3 days it has started to turn black. Not sure why this is, but I'm concerned it may be mold. Though i have read that this can be caused be deteriorating choloraphyl, which would make sense because it was trimmed fresh. Has anyone else...

[/IMG] Hey there, I have been reading posts on this site for about a year and was finally spurred to create an account when my plants had a problem I couldn't identify. My setup was 4 plants being grown in coco, with drip irrigation and Botanicare nutes with an EC of 1.6 and a PH of 5.7. Two...

My plants were just doing fine, recovering from a nitrogen deficiency when I noticed these black spots. In addition, the leaf tips are also turning yellow. First it was only on the lanky one and now its on the healthy one. I was wondering if you guys knew what this was. I did research, and I...
