WOW!!! My bad.... When I clicked on the first page of the thread it took me to the last post, and I thought that was the first post.. DAhhhhhh. Still are you useing R/O water???? Also I could not find a picture.. But even then. the only syptom that I know of that has little spots is Calcium defieciency.. But then again I suck at being a Plant Doctor. My last crop was 8 plants started, 7 were male, the female for some reason would not fully mature. That WITCH grew to almost 7 feet tall, 3 foot in diameter, and full and bushy,, looked very healthy also.. But the buds were light fluffy and mostly stems. The buds were as big as my arms until I started to manicure them. I finally came to the conclusion that is was just the gene in that one plant,, and I am sticking to it... HAHAHHAHAHA...

Would like to see a picture of your plants though.

hmmm i would initially agree with widowmaker, i have had tiny spots in the past but caused by pests (spider mites and/or aphids) but if the head leaves are turning brown and crispy? i would immediately think they are too close to the light. a yellowing of the older leaves can be caused by either: 1)a shortage of nitrogen 2)pH factor is too low(acidic) 3) iron deficiency 4)pot defic. especially if you also get a grayish brown spots... on the edges of the leaves. 5)magnesium defic. if their is a yelowing around the veins at first then spreads out to the edges.. if the tips of the newer leaves are turning brown it could be a simple matter of drainage and/or over watering, but i am sure this won't be an issue for you, being a more experienced grower.. good luck!

one other thing to be aware/mindful of is fungus and spots/moulds... there are various forms of mould and growth that form spots on the leaves etc.. e.g. leaf spot, elsinoe spot, black spot to name just a few.. might be a good idea to purchase a good organic spot and mould-fungicide. also good for flower blight, rust, septoria, blights (both early and late) and downy mildew... good luck

did you get rid of your tiny little yellow spots and brown how did you do it ?> I have the same thing happening with mine.

I have got little yellow spots and the leaves are loosing colour. I have attached photos so people can take a look. Any advice would be greatly appreciated. I was wondering if its a nutrients problem, or if it is an insect problem. There are little black bugs, but not sure if there are enough to be causing that much damage. please help.
