Light colored sugar leaves

Nitrogen will be pulled from the bottom of the plants leaves first. It's not nitrogen. That's impossible to have nitrogen faded leaves on the tops but nice green lower leaves. Is it more noticeable on the tops that are closest to the light or is it on lower bud tops as well? Is it on all the tops, or only the lower buds that get less light? You have very mild tip burn on your plants. I would think the yellowing is caused by hot soil. The rest of your plant looks nice and green yet the tops have that yellow small leaf thing. If it's a nutrient deficiency, its a immobile one. So that eliminates half of the possibilities. So when someone says it's magnesium, you can laugh at them and tell them to fuck off. This isn't a simple one to figure out cuz the rest of your plant looks great. I can't see up close on the over all shot of the plant but the close ups you do show seem to be lower bud tops on the plant, and not the big tops closest to the light. It could just be that those lower buds aren't getting as much light. I doubt it's a pH problem because the plant over all looks good. It's not a root issue. It's not a heat or cold issue. It's not too much light. I think it's just lower light levels on those lower tops.
