A question from a fellow grower:
Looking for some advise here. My setup is as follows. Grow tent is 3X3x7 and I am using a 400W Metal Halide lamp. Single plant per pot, pots are probably 3 or 4 gal in size. I’m using Miracle Grow potting soil with moisture control. Don’t know what the PH of my water is as I have no tester. Humidity has been running 50 to 58 percent and I have not used any nutrients as of yet. I don’t know what strain this is, as I got it from a bag of Mexican dirt weed. The plant has grown nicely and has many blooms on it. About 3 weeks ago, I noticed these brown spots starting to grow on a few leaves. over time it is getting worse and spreading and I can’t find anything online in any of the blogs or forums to tell me what might be happening. I was hoping someone here could tell by looking at my pictures. Also, I am growing a couple of White Widow Autoflowers that I purchased from you. One WW has grown to a height of about 11 inches and is getting covered in buds, just not growing much. The second WW has been on a growth spurt for the last 2 weeks and just amazes me everyday. It has grown an average of 1.7 inches every day. In eleven days it has gone from 13 inches tall to 32 3/4 inches tall. WOW! It is also forming buds up and down the stem as it grows.
