From what I can see when I put my eye on the screen, lol, is what looks like magnesium deficiency. Try mixing one tablespoon per gallon of epsom salts into every watering. You can also get a sprayer and apply it as a foliar spray at one tbsp per gallon. The damage will not reverse and when caught early does not affect overall health.

Alright thanks I'll give it a shot

From what I've read Calcium and Magnesium bond together, so you should probably pick up some CalMag. Also if your ph is off it could be preventing nutrients from being absorbed and cause future deficiencies.

I just take water bottles and let them sit for 24 hours. I never tested the ph just because I never picked up a kit yet

I did that with my last grow. I let my tapwater sit out for 48 hours and just used that. Upon noticing some lower leaf twisting this grow, a sign of PH issues, I purchased a cheap PH tester, the vial and dropper test and my water PH is easily above 7.5. I've been dropping it down to around 6.0 with apple cider vinegar, about a half teaspoon per gallon.

I'm pretty sure it's what has been causing a few problems for me.

I just checked the ph Of the water I'm using with strips and it's around 6.6. Is that what is making my leaves turn orange?

I believe 6.3 - 6.8 is good for soil, or at least Fox Farms. If it's magnesium then use the epsom salts or CalMag.
