As my grow shelf becomes fuller and fuller...whenever I try to manuover the spray bottle around inside...my hand hits the talang that is in the center of the tray. As a result...it acutally stalled for a little while and is finally starting to grow.
During that period...I noticed this: The dots on the leaves which appear only on the older leaves (3 leaves older than the growth point) got even more intense.
Please see this. What can I do?? Is it rust or is it leaf spot fungus? (CLICK TO ENLARGE)
Can i just use a standard fungicide spray?? We have a spray called DEFENDER available:
Safer's® Defender Fungicide
Safer's® Defender Fungicide is a liquid, sulphur based fungicide which controls the most common surface infecting fungal problems such as powdery mildew, black spot and rust. Defender actual defends the plants by covering them with a protective coating. This product is ideal for roses as it does not have the strong smell often associated with sulphur based products. Defender is available in either a ready to use or a concentrate.

Regardless of if it is rust of a spot fungus, a normal broad spectrum fungicide should do the trick. I'd hit it with something with whatever the recommended dose is. You should do it as soon as possible as well. When summer rolls around and it is hot in your chamber, it will further weaken the plant's immune system. If something like that is already present, then you might have to bid the plant bye bye.
