I don't know about nutrient lock out. People keep using that term, but it looks to me that the OP is poisoning that plant with too much stuff. I think that's all there is to it. Over fert is shown in dark green leaves with yellow/brown leaf tips, and that's what we see in the photo.
We kind of all said that right away after the original post but the only response from the OP was to invest in more products of the same line and what ppm to give to “balance the plants out”.
Nutrient locknout is simply too much crap built up in the medium and blocking the roots. Nutrient antagonism is when too much of one element blocks uptake and production of another element. Or nutrient balance needs restored is a phrase I see.
We all seem to over invest in the beginning and then of course want what we bought to be right and work. But we eventually figure out how to read plants and what they need to be happy and productive and hopefully stop force feeding them and grow them to their potential.
I was the opposite. I was a gross underfeeder in the beginning. Afraid from all the burned plants I saw online all saying to add more cal mag. Lol.
