Pale leaves and some clawing

You are in coco, I am a coco grower. So the information you need is your ph is off. Keeping coco wet is right. Other guy didn't look at your diary, and don't know how to grow in coco apparently. You need to flush the substrate with a 5.8 ph water. Do this till run off reads 5.8. I use strong ph down then level it out with 5.8 once I get it right. Then reapply nutrients with a cal mag. Coco is heavy irrigation. Just do NOT leave it sit in run off. I run this cycle every other day on them. Keeping them wet between feeding. She will perk up once this is done.
