What is this voodo magic bullshit

Ok, im new here and new to the green thumb scene, what is going on here, one day i find a yellow ugly leaf with green veins, 3 good days go bye and there looking good. I put a very small amount of nuts, like 1/8 of a tbs yesterday, when the plant looked good. So today i went back and found 5 more changing, i dont get it, my soil has a 9 month slow nuts release. The only time i put nutes in the feed was that one time, was it not enough?? Or has it not did its thing yet??

Where were those leaves from on the plant?

Looks like you over did the nutes imo.

EDIT:

After reading your other thread. No I think nothing is wrong. Leaves turn yellow and die as a normal progression of the plants life.

There were near the all over in different areas, its from the cheese, im hoping its not the nuts, im new and does nut burn kill the whole plant or just some of it?? should i flush asap even though i just gave them water yesterday??

that's not a burn it appears to be deficient, feed again but with a little more, maybe 1/4 tbs. Its been a few days so its not too big a surprise you need to feed again, Only gave them an 1/8 of a tbs after all
