Hello everyone I'm a new grower. I am growing eight plants. I was told the strain is blue dream. I'm using fox farm ocean forest soil in 5 gallon pots in a 4x4x7 tent.I vegged for four weeks with no added nutrients. I'm now 5 days into flowering and I have now added nutrients once. I'm using a 1000 watt HPS with an 8 inch yield master hood and a 740 CFM inline fan. I have a 8 inch booster fan at the top of my tent pulling hot air out. my temperatures have been around 77 degrees during the light cycle and my humanities been about 40 to 50 percent. I'm having trouble with a couple of my plants the leaves are turning brownish and very brittle. If I squeeze them they crumble like they're all dried out. I noticed that the plans that is the worst was right next to my oscillating fan which I had on the highest speed. Does these images look like wind burn?
Wind burn would sound right if its the only ones and are all fed and treated the same. Sounds like you have a good set up. Might dial down the fan.
I turned down the fan yesterday. I noticed a few others have 1 or 2 leaves like it but the one closest to the fan was the worst.
Wind burn made it worse ...treat as for severe nute burn and flush to my blog: http://forum.grasscity.com/blog/1093/entry-9829-flush-baby-flush/
