Need help! What's wrong

Hi Im wondering what is happening with my plants? I was told the pots aren't big enough (5gal smart pot fabric) and then I was told it's the heat (88-93 degrees) we feed them Around 1700 ppm of nutes every couple days and we have a 1200+ ppm of CO² in the room. Can any one shed a light? We are using HPS bulbs about 2 feet above the plants

Kind of looks like chronic underwatering

1700 ppms is to much nutes.
Your burning them.
Plus high heat isnt helping either.

They are watered almost everyday with water between 5.8-6.3ph . But I will definitely look into the watering schedule closer, thank you for the suggestion!

Even with the 1200+ CO² ppm in the room?

Also my A/C is broke rn aswell that's why the temps are so high .

How are you mearsuring and controlling Co2 levels? Looks like something is off and they are much higher than you think. Over-saturation cause the stoma to shrink. Restricting transpiration.

We like our buds well done, but damn........ not leaves
