So I have experience with soil growing... I may just stick to it.... I had some freebie seeds from nirvana so I got a wild hair and decided to do a Rubbermaid tote style setup. They really took off, but recently I first noticed some rust spots on the lower leaves, and then some lighter green "tiger stripes" on the upper leaves. I was thinking nutrient deficiency. I know some of you would shoot me for my ignorance, but I was really keeping this simple, kinda like a side hobby from my main grow, so no, I don't know ec, ppm, or such crap. I do keep an eye on ph, and it has been good. Any tips?
