You got a few issues. First you where in nitrogen toxicity at one point then now I think you ph is out of range. Possibly from lack of run off. Not sure. Usually the sign I see with deficiency and nute burn signs at same time. I put my bet on nutrition build up in your substrate causing ph swings and lock out.
it's kind of all the problems... Looks like a bit of pH fluctuations, too much N, not enough PK, not enough calmag... fix them all and you have a small chance to get something smokeable 🚀
