K deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?

Magnesium deficiency, not potassium defciency. In soil grows, a pH of around 6.4 is ideal, 5.7 in soil is way too acidic.

Hola! controlas el pH del agua? puede que no esté correctamente y las plantas no estén aprovechando eficientemente de los nutrientes del suelo. El valor en esas semanas suele ser alrededor de pH 5.7. La fertilización no es probable que sea porque se las ve bien desde el centro. Controla los valores de temperatura y humedad, no se ve muy grave.

It looks like a K deficiency. Could be a possible lockout of K .
