Are you giving just plain water for now.
You should need no nutrients for 4 to 6 weeks with HF.
You have some high ppms mine is in the 350 ppm range. Because of this i give no calcium so no calmag. I do give magnesium by adding epsom salt. I find my girls to need mag to stay looking good under a lot of light. I raise in promix Bx and the FF trio supplemented with epsom and sometimes molasses.
What nutes are you going with when it’s time?
I think it looks good right now.

508 PPM tap water is incredibly high. Probably one of the highest I’ve ever seen. You should be okay throughout the vegetation stage and/or until depletion of your pre-charged nutrients in the soil. (Whichever comes first)
Moving forward, with a PPM as high as 508 when it comes time to feed you’ll have very little room to add nutrients. Once your nutrients have depleted the soil you may want to start cutting your tap water with 50% distilled water or RO water. This will reduce your water’s PPM to 254 PPM (still a high ppm)
Or if you plan on growing much, invest I a home RO filtration system.
Just my 2 cents

Is this well or tap? That is a very concerning number.

That’s incredibly high Growmie…tap or well. If that’s your city tap source I would request a water quality report. Border line toxic levels in my opinion

My tap water is 250 mostly calcium. So I use gh trio with low calcium. But when i read my final numbers I subtract my 250 from the total number. So a reading of 950 is actually 700 ppm nurtients I want. I grow hrdro and it wotks great for me.

Just tested my meter in distilled new water reading 0000 for ppm now . Should I add cal mag to next watering for my plants

From the pics, I would give them 150 ppm of cal mag, and recheck your runoff with the good meter so we know where we are .

Is there an amount of cal mag that would equal to 115 ppm specifically or just slowly add till you get the number right. I’ll have to wait til my next water soil still has time before watering again forsure

Take a gallon of water, distilled if possible. It’s going to be 0 EC and 0ppm. Add exactly 1/2 teaspoon cal mag , stir and check. That will tell you exactly what EC or ppm 1/2 teaspoon per gallon will give you, then it easy to do the math to get to 150 ppm or 300 EC. If it checks at 75 ppm, you would need a full teaspoon to get to 150……

Your plants are exhibiting symptoms of high heat and overwatering.
High heat symptom is the serrated edges starting to turn up or taco.
Overwatering symptom is the edges of all your fans are light green to yellow. Just starting so easy to fix. Let her dry out before watering. You are in soil correct?
