Help diagnosing possible nutrient deficiency

[Growin_Rouge]

Currently 18 days into my first grow. I'm running 2 moby dick xxl autos from dinafem in 5 gallon pots with coco and perlite. About 7 days ago i noticed some discoloration starting between the veins on my first set of leaves nothing to severe but it was noticeable. Since then all new growth has been normal and healthy and the discoloration has stayed about the same. To me it looked like a magnesium deficiency based on the reading i did but being new to all this I'm not 100% sure. Anyone got any knowledge and insight they could drop to help out a newbie?

Plant looks awesome . Some strains will do that w the first set of leaves it's totally normal. As long as it's only that first set it's all good

OK good at least you're feeding them something. Plants look good. I don't think I would worry too much yet. New growth looks great. I think I'd wait and see what happens to the fan leaves before I changed much.
