So I noticed some yellow brown spots on the leaves of a few of my plants just now. Here are pictures:
I checked this forum and read the guides, particularly this one: https://www.rollitup.org/marijuana-plant-problems/150004-plant-moisture-stress-symptoms-solutions.html
It mentions - "Over-fertilizing - the most common cause of leaf cupping aka leaf margin rolling, leaf margin burn, and leaf tip curl/burn is the overzealous use of too much plant food in relationship to factors such as plant size, vigor and rate of growth. The first unit of a plant to show moisture stress is the leaf at its margins and/or tips, reflected by margin rolling (cupping) or burning. Sometimes copper colored necrotic spots show in the leaf also. A hard, crispy feel to the leaf frequently occurs as well, as opposed to a soft and cool feel of a happy leaf. When you have a high concentration of salts in solution (or in the root medium) compared to lower salinity levels found in the plants tissue, water is actually drawn out of the plant across the root gradient in order to fix the ppm imbalance. IOW, this is a natural, osmotic response that serves to equalize salinity levels on both sides of the roots epidermal gradient. Back off on the amount and/or frequency of plant food. Too much plant food can also burn the roots, especially the sensitive root tips and hairs, which then creates another set of problems such as nutrient deficiencies. A note for the bio folks - as soil dries, the concentration of the remaining salts rises further exacerbating the problem. Leach (flush) your pots once in a while to get rid of excess salts."
The bolded part up there best describes my situation, I think. Copper is the right color to describe the necrotic patches.
Thing is... I haven't fed nutrients yet. I'm using Fox Farm Ocean Forest and my plants are about 2 weeks old. I wasn't going to feed nutes for another week, and I've only been watering every other day, except for yesterday. I watered a bit more than usual, and I had watered a little bit the day before. Could that be the problem?
Think they'll be fine if I just leave them without watering for a few days?

Far as Busted's problem I thinking fed it you haven't fed in 2 week. I fed at about 1.5 weeks. It wouldn't let me put my video here but here's a link to it! FFOF just not what used to be!
