Possible deficiency?? 5 galsuper soil c99

Hey guys these are my wives 2 plants, there in 5 gal dirt pots about a 1/3 of ss maybe a tad bit more wich worries me, cooked the soil ina garage but dont know if it usable.
The problems started with the bottom firs set on one but now both are showing same signs
Looks something like this..( srry don't know if i posted this right)
I just took the tds and ec of the watter it read ppm 234 and ec 452 off wallyworld brand springwater , she has ised nothin but that to water.. any suggestions guys??? I know they’re young but its getting worse... i fear too much ss or baybe ocerwatering and leeching the nutes to the bottom as they’re outdoors and need lots of water.. im actually impressed because these babys have pulled through over 100f heat for a good while now but do to storms dropping temps down outdoors im not so sure they’ll keep loving the heat, they hated my indoor setup though through those 3 days

Honestly, they don't look bad. Maybe when they were younger they didn't like your soil (tips burned on some of the oldest leaves) but they look decent enough. I'm not sure I'd do much except watch them.

Thanks.. ill keep an eye on them these next couple of days, i want to start using tap water though, using spring water is getting a little pricy
