my questions are how often to water and which ph works the best?

cheers!

Just looks like coco pucks to me, you can get those at lowes. PH6.3 water depends on environment.

i'm also using canna products that say the ph should be between 5.2-6.2 so i have it at 5.8 at the moment because my plants are in veg. the problem is that they are suffering and growing slowly and i think i've got ph issues or something else i can't figure out.

There are lots of factors that could cause this but i wouldnt blame PH. Dont over feed dont over water and give plenty of light.
