Losing vigor and yellowing

Sorry I don’t have a diary for this grow. I did collect some runoff on one of my girls so hopefully this can help for giving assistance. This is only my 3rd grow and the first 2 went very well but this one isn’t, all plants have lost vigor, are growing slowly and are yellowing.

Anytime you get into the 5ph range you are in risk of aluminum toxicity, which reduces the plant's ability to absorb water and nutrients, such as phosphorus, magnesium, and calcium. Sulphur is an immobile element in the plant. Availability decreases below pH 6.0. I'd add some sulphur, often overlooked macronutrient. Looks like it to me. Good nitrogen sulfur fertilizers include ammonium sulfate, calcium ammonium nitrate, and YaraBela fertilizers.
