Initially without detailed info looks like a calcium deficiency as it’s on top. Could be other deficiencies as well and could be an out of balance in nutrients causing lock out or due to PH.
My guess anyway

Just pulled out my soil ph tester and the root soil ph read 7.2 on the plant with issues and 7.4-7.6 on the others. I think i should most likely flush but i just watered yesterday, would it hurt the plants to go ahead and flush now or wait another day? (i give each plant a gallon of water every 3 days)

If by chance your using tap water from a municipal water supply it normally contains a fair amount of calcium and that can increase PH over time. Even if you use some sort of PH down like citric acid or another type and you lower the PH to 6.5 for example your still adding calcium and it buffers things and can raise PH.
What soil meter are you using and do you maintain it cleaning after each use and not leaving it in soil for extended time and before using next time using a green scrubby pad to clean any oxidation that occurs on the probes.
Sometimes they work and sometimes they are off.
