What’s happening?

So the leaves have been yellowing and drying out for a while now I’ve been watering with 6.20 ph water the soil is Dr. Coco no nutrients just a lil but of cal mag

The plants need nutrients. The yellowing is Nitrogen deficiency. The leaves hanging straight down parallel to the main stalk is from under watering.

Is medium coco?

You plant is saying , Feed me! You have a Nutrient def.

Do you water til you get runoff?

What do I feed them for nitrogen deficiency just water?

I do water until just a little bit of runoff like minimal
