Shortcut: To early, to much_, lockout. Long version. Your soil contains enough nutrients for minmum 4 weeks. The plant can handle to grow longer without extra feeding.( 18 l soil) The nutrients adding up. a+b +B52 adding up to 5 percent N and they get a big amout of it( 6ml) and that is only one Nutrient. If you start feeding it better to use inly 25 percent of the amount that the company recommends. I would recommend to you, stop feeding, purew water for 10 days, and then start slowly with a and b and voodo juice. B52 you can add if she is in the stretch. The water,,, maybe a mistake=? in writing? if not pls reduce drastically 200ml should be enough for 2-3 days. The Light distance looks good. your plants should stretch a little to the light( you see it on the space between the nodes. and the leaves should look good and flat ( no cupping). If they start to cupping/ tacoing the light is to near. Happy growing
