I'm thinking cal or mag deficiency? Growing in coco perlite mix feeding once a day in 5 gal fabric pots, ph5.8 to 6.2 Rh 55 temp 23 degrees. Any expert opinions appreciated

That's too much dry back for Coco. Are you growing photos or autos? And when you water how much run off are you getting and have you checked the run off EC?

You look like you in about week 4-5 of flower, feed them base nutes 2 ml of A + B per litre with 2ml of bloom additive. Increase watering to 8 times per day. Add cal mag but also at about half the recommended dose. Cut dose in half if they are autos.

Looks like moisture stress. Could probably water more often as Kola said. Once a day may not be enough especially in coco.

Good luck
