Leaf veins seem to be getting lighter or am i imag...

Hey there Kenethica, yeah good job noticing you're in a practically soiless medium, that means you need to supplement NPK, which you've been doing as well as supplement micro nutrients that's (calcium , magnesium, silica , etc) but what folks forget is that you also need a chelation agent because the medium is inert ! The yellowing between the veins affecting the oldest leafs first is a sign of magnesium deficiency which is expected as you've not been feeding any. Second, those leaf curling like that is a sign of root problems, probably you're keeping your pots moist which is a no-no : you need to have a strict wet dry cycle. I recommend watering much much less but more frequently like twice a day. To fix the root problem you'll need a chelation agent. This will break down the problem roots and turn them into nutrients for the plant, i recommend something like humic acid or enzymes. So remember : three categories of things you need for soiless grows : NPK, Micro and Chelation Agent. Hopefully the little guy will recover, but it'll probably be stunted... try keeping it alive but when you got all you need, start another one, that's my best advice. Hope this helps ! 🚀
