First grow, need some help with organic defeciency

I am doing my first grow and am 6 weeks into veg in a FFOF and FFHF soil mix in a 7-gallon Smart pot. 2 weeks ago I top-dressed with 1 tbsp Alfalfa Meal and 1 tbsp Kelp Meal. I also added 2 tbsp ground malted barley a few days ago and plan to continue that every 2 weeks or so. I believe I went a little heavy on the alfalfa and ended up with some burned tips, and I'm aware of that, but over the last few days I have noticed brown spots showing on some of the leaves that look kind of like a calcium deficiency to me. These leaves are also getting lighter in color. I have included pics, but it looks worse IRL. Soil ph is at 6.8 and all new growth looks good. What do you guys think? I'm doing my best not to overreact and make things worse adding things it doesn't need haha.

Those leaves don't look bad. You don't have to add anything to ocean forest provided you use a large container and enough of it to last the entire grow. Don't bother putting up pics that aren't in white light. color is too important to diagnosis a problem properly, and that won't happen under LED. If discoloration continues to be a problem, it's probably because you added that stuff. If the temp is too warm on the leaf surface, that will cause burning of the tissue and browning color.

Thanks for the reply! The leaves have brown/black spots and are yellowing. Everything I have read said that around 5-6 weeks you need to supplement nutes, even with FFOF. Hopefully that wasn't a mistake haha. New growth isn't showing any of the issue. I added some more pics from today, it has gotten worse and should be easier to see in the pics now.
