tips of leaves pointing down. having trouble fixing

Thanks in advance for any help.

The tips of the fan leaves are curling down looks like it could be a ph issue but its been 5.8 steady. Also had them up to 1100 ppm dropped them down to 900 4 days ago.

things look fine to me. you cant expect perfection, remember this the enemy of good is perfection, you cant get it perfect. but the plants look fine to me my plants do it too but I grow outside so there might be a difference. plus I have shit for soil and that doesnt help, but I wouldnt worry. but if anyone knows something I dont let us know.

Fine fine. not a problem there.

Wait a few extra days before watering and then give her a treat like a very dilute molasses tea, algae tea, worm casting tea. Dilute is the operative word.
