Suspected Nitrogen Deficiency

4-2-4 (x1) 0-0-2 (/2) and 5-1-4 (/2) your weighted average ratio is 6.5 / 2.5 / 7 -- at least the one week i looked. you have soil and soilless components, so you get a little nutrient right now from the soil. i'd suggeset shitting or getting off the pot and just do soil or soilless. you'll never find a goldielocks zone with that ratio. Below is more suited for a soilless context, but over time things have to average out in similar ways as far as provision of nutrients vs use of those nutrients in the plant. When you get around 120ppm N with that ratio, you end up with 16ppm P and 107ppm K .. probably too little of each. However, if you try to raise those up you'll end up wiht sky-high N ppm. Doomed if you do, doomed if you don't. This is asking for an entire grow of constant adjustment and it'll get much worse over time as things build up in substrate Now, since you are in soil and don't fertigate every time, there are other components to consider. Definitely a N-deficiency here. I'd suspect that's more about waiting until nearly the 3rd week to fertilize? But the current ratio of nutes is going to inevitably run into issues.
