I have setup an indoor room to grow in and have a few plants in there.
I have a problem with the leaves and I am not sure what it is. I originally thought it may have been too much nutes or spider mites. Have sprayed plants with pyrethrym and also flushed out around 5 days ago with plenty of fresh water. Have not given any nutes since. It appears that the leaves are still doing the same thing however.
I have attached a pic showing a few leaves, they kinda look yellow and also they have spots forming - some of them got quite bad before I sprayed/flushed and it appears they are doing it again.

Any help would be appreciated.

How much ventilation do you have?

Is your fan blowing on those plants all the time?

I don't have an inlet fan hooked up yet. I have an extraction fan however that comes on about every 3 hours or so. Room is about 2meters by 2 metres by 1.7 metres high. I have a fan blowing in the room however it is a high fan maybe 1 metre off the ground as thats all I had around - so it kinda blows down on the plants. It is on 24 hours a day.

Could this be the problem? I have got an inlet fan here just havent had the time to hook it up. And can get a smaller fan that is at ground level if it would help.

You could have problems that stem from lack of proper ventilation. You must have intake as well as exhaust and need as fan blowing on your plants all the time. I lost a grow to fungus because of this.

OK , I will get a smaller fan that will sit on the floor and try to hook up my inlet fan. Hopefully it will help a bit. Should I see improvements straight away? Or what kind of timeframe?

I didn't see improvements at all. But then mine got real bad. It was diagnoised from nute burn to spider mites. That entire crop was pretty much a bummer. But this is how we learn. I seem to learn the hard way a lot. But it sure makes an impression.

Thats no good. I would hate to lose a crop but as you say it makes you learn. I have not grown indoors before so this is kind of a small test run. I have six plants from seed they are approx 6 weeks old. I wanted to do a small run first to iron out the kinks and get the setup perfect. I also have a hydro setup waiting to be used also, so ultimately once this crop is done I can start a fresh and grow some goods mothers from seed and then take clones into hydro. Once I start my next lot I may start a grow journal also.

Thanks for the help I will let you know if it has done the trick in a week or so.
