Northern Lights Auto

Dude I noticed you have a similar "white patchiness" in some of the leaves at week 3 that mine have in most all of the plants, but mostly in 1. I self-diagnosed it as TMV (Tobacco Mosaic Virus) and was convinced that it was that. However, since then, you're the 4th person with Seedsman Auto NL seeds that also exhibit this characteristic, but for yours it seems that it has mostly disappeared as it approached flowering. I also am in the 1st week of flower for most of my NL Autos from Seedsman (8 plants) and am showing those brown spots that I assumed was a calcium deficiency. Also, some of the lower leaves on many of the plants with the brown spots are yellowing and eventually crisping and dying. I am currently using 1/4th the recommended dosage of nutes out of fear of burning them. It's weird because the same plants that I assume are deficient and showing the brown spots and yellowing leaves at the bottom also have a slight burn on the tips of the leaves. I am growing in a 3:3:3 mix of compost, coir, and perlite however. Not sure how advanced of a grower you are, but do you have any advice?
