Original fan leaves yellow and dry

[Septooth]

Is it normal for the original fan leaves to turn yellow and dry out?

Girls are 32 day old cream cookie autos. They are in OF soil and have been since birth. Been giving them water PH'd at 6.3.

- nope, something is wrong here... Since it's the very iffy OF soil, my first suspect is off-pH, plus the pH water going in is too acidic.... OF has shown to be badly off pH at times, very inconsistent; some get OK bags, others get shwag!
Any nutes going in at all? It looks like a more atypical showing of P defc. to me,.. could be lack-of, or locked out from low pH in-pot...
You'll need a good soil pH probe for this, run-off isn't a reliable method to check pH in soil... The Accurate 8 (CPW) is a good unit for the money, avoid the skinny cheapo units for this they suck!
