Hey Manapool, you have the start of a magnesium deficiency , i guess because of two reasons : first reason is the light is very strong for a small plant so the plant is getting stressed and needs more magnesium to grow. Second reason is the feed you're giving is good for the rooting process, but the problem is it raises the pH and the higher pH makes absorbing the magnesium and calcium almost impossible for the plant. I guess you're not pHing the input feed right? So my advice is to add cal mag and cut out the rhizotonic , make a spray with 2ml / L cal mag a spray it on 2 or 3 times a week. The problem should stop spreading within a 10 days or 2 weeks. Hope this helps ! :rocket:

Hey there so i agree with the look of mag deficiency, whenever the leaves have that margin discoloration (it always looks like a grid to me) i think mag. Its often with other deficiencies too and low ph. If your roots are incapable of absorbing it i would suggest doing a foliar application (close to lights out though) like you're doing...but maybe try epsom salt rather than an actual calmag sup, as E.S is mostly just magnesium.
I see you dont have a ph listed, if ypu don't have a pen maybe you can get your local water report to get the starting ph? I think mag does best 6.5-7. Finding a very finely ground dolomite lime to add to the soil may be the best option if ph is unknown as it helps to buffer the soils ph. I

hope you find your troubles and can fix them. :v: I know ph can be a nightmare, but it definitely helps rule out a lot of problems. Happy growing
