Thrips!! Hey there, I discovered, that my plant has some thrips damage, I also found 2 black ones and a handful smaller white ones as well as their shit!

That's not from pests. neem is ineffective if it is "clarified" or otherwise missing the active ingredient, which is often the case. My state doesn't allow the sale of 'real' neem oil. An 'uncomfortable' environment relative to a pest won't do much either. pyrethrines are a good option - kills on contact. Nothing is 'safe' to use on flowers, if/when they exist no matter what the package says, FYI. interveinal chlorosis with spots does point toward Mg deficiency. If the plant is not old enough, it's more likely something else. Mg issues take 30+ days to be visible from the point it was deficient. This plant looks too young for that. How it progresses will help eliminate possibiities.

that's not looking like thrips to me. its looking like calcium with some Magnesium issues. I don't think neem is going to do jack shit no matter how you apply it to fix that problem. Check your nutrients NPK breakdown and for 2ndary macros. Plagron is famous for making it not easy to find. its annoying.
