First time growing in coco

So this will be my first time growing in Cana coco brick and my leaves the serrated edges on some leaves are curving down
And the plant on the right the leaves feel more dry then waxy to the one with the curling sides
My light I’m using is a aglex 2000 watt in a 4x4x8 the light is at least 4 feet away from the plants tent temps are a steady 25 degrees
RH 53%
Feeding them connoisseur ph perfect grow A-B advanced nutrients at 2ml each in a gallon of water and feeding 0.6ml of B-52

Whats going on with your pH...

I cant get much info from pic. You may be noticing something really early in its manifestation.

Sometimes the downward curl is pH related. Sometimes happens after a heavy feed too or salt build up in conjunction with pH issues.

My ph going in is 6.0 5.8 and when I check run off it’s at 6.4 and I water with a gallon of water every time so I get a lot of run off to not have any salt build up should I lower my ph more until the coco ph is down to 5.8

Ph curl, you can try giving them clean water with some runoff to see if there’s any salt buildup in the coco.

Use a PPM meter on your run off. It will tell you if you're overfeeding or not. They look fine to me. They are praying, maybe not as much as they could but this is your first run and it takes experimenting to figure out what they are going to like. You can play with that using a pH meter and PPM meter testing run off. And if you have a brix meter it can help too. But IMO you're doing fine and will be happy with the end result if you can keep them looking like that.

Okay thanks for the replies I have a Ppm meter and a ph pen ppm coming out at like 150 and I’m feeding basically at that I get lots of run off everyday I water I just hate how some of the leaves look like that
